2DSOTECH - 2Dimensional van der Waals Spin-Orbit Torque Technology

Dvojrozmerná van der Waalsovská spinovo-orbitálna torzná technológia

Duration: 1. 12. 2021 - 29. 11. 2024
Program: ERANET
Project leader: RNDr. Gmitra Martin PhD.
Annotation:Engineering two-dimensional (2D) material van der Waals heterostructures by combining the best of different functional constituents can offer a plethora of opportunities in nanoelectronics. Here, we propose to develop all-2D spintronics platforms for the next generation of information technology based on 2D magnetic and topological spin-orbit materials. These hybrid systems can provide a strong synergy between spintronics and 2D materials, with the goal of combining “the best of both worlds”. Such integration of spin-orbit physics and magnetism in 2D heterostructures will enable groundbreaking functionalities in all-2D spin-orbit torque (SOT) technologies for low-power and non-volatile memory and logic devices. We will exploit low crystal symmetry of layered spin-orbit materials (SOM), hosting novel spin textures for the realization of efficient charge-to-spin conversion (CSC) with a significant out-of-plane spin-orbit field contribution for SOT technologies. We will start with basic investigation of CSC by using potentiometric methods in non-local spin valve geometry with graphene heterostructures. These studies will provide information about the main driving mechanisms of the CSC phenomena, such as the spin Hall, Rashba-Edelstein, or other spin-momentum locking effects to generate a giant and tunable spin polarization. Magnetic 2D crystals, on the other hand, exhibit a wide range of magnetic ordering and, extraordinarily, have the potential to be controlled by purely electronic means. Here, we will investigate 2D magnets for SOT technologies exploiting their low-dimensionality, perpendicular magnetic anisotropy, and the possibility of electric field control. We will examine the dynamics of magnetic excitations, their anisotropies, and controllability by gates, the critical parameters influencing the magnetic switching speed. This project will integrate 2D magnets and SOMs with engineered interfaces to establish exceptionally efficient SOT switching functionalities in all-2D materials platforms. We aim to study the fundamentals of magnetization dynamics and SOT switching behavior of hybrid structures using electronic, magnetotransport, time and spatially resolved magneto-optics, ferromagnetic resonance and 2nd harmonic measurements. The potential of the novel functionalities in these heterostructures will arise from the interplay of exotic spin textures, magnetic phases, proximity-induced exchange and spin-orbit effects at the interfaces of the 2D materials. These effects will be further controlled by interface engineering with a graphene interlayer, twist angle between the layers, and with external parameters such as electric field and pressure. These functionalities will be complemented with voltage-controlled magnetization switching in ultrathin devices. Finally, we will utilize these engineered hybrid devices to demonstrate ultra-fast and low-power magnetization switching of 2D magnets, for a future generation of all-2D SOT technologies.

Annotation:Cancer is the second leading cause of death after cardiovascular disease in almost all European countries. Over the past several decades, the principle types of cancer therapies have been chemotherapy, radiation therapy and surgery. This project is focused on the development of biocompatible multifunctional magnetic nanoparticles and evaluation of their diagnostic and therapeutic potential for the application in oncology. The first step to achieve the desired goals will be the synthesis of magnetic nanoparticles and the functionalization of their surface with a suitable biocompatible materials suitable for radiotracer binding. Several physicochemical methods will be used to optimize the preparation of biocompatible multifunctional magnetic nanoparticles (MNPs). At the same time, we will study the suitability of multifunctional magnetic nanoparticles for magnetic resonance imaging and magnetic hyperthermia application as well. Considering the application purposes of biocompatible multifunctional magnetic nanoparticles, biodistribution studies of radiotracer conjugated MNPs will be conducted. The prepared radiotracer conjugated MNPs will improve the efficacy of cancer diagnosis and treatment. Moreover, combination of MRI, hyperthermia and radiotherapy represents a significant advance in cancer diseases treatment and a substantial improvement in survival of oncological patients. The project is based on a complex multidisciplinary approach,ranging from physics, chemistry up to biochemistry and biomedicine. The involved partners possess key skills, infrastructure and are highly motivated to reach the project goals.

Duration: 15. 11. 2018 - 31. 5. 2023
Program: European Space Agency (ESA)
Project leader: Ing. Baláž Ján PhD.
Annotation:The ESA’s JUICE (JUpiter ICy moons Explorer) mission (http://sci.esa.int/juice) have to face to very hostile environment of Jovian radiation belts where the penetrating energetic electrons dominate. The Particle Environment Package (PEP) payload of this mission (http://sci.esa.int/juice/50073-science-payload ) is under development within a wide international collaboration led by Swedish Institute for Space Physics IRF in Kiruna. Due to limited available mass for efficient radiation shielding, the PEP payload will operate in rather unfavourable environment of penetrating energetic electrons that will affect the detection process inside the PEP/JDC (Jovian plasma Dynamics and Composition) sensor. To mitigate the unfavourable influence of the penetrating electron radiation to the plasma ions detection process, a concept of anti-coincidence module (ACM) has been identified within the PEP consortium. The project involves development of space-flight grade semiconductor solid state detector, the processing electronic board and a laboratory testing and calibration system RATEX-J (RAdiation Test EXperiment for JUICE).

Duration: 1. 1. 2021 - 31. 12. 2022
Program: Mobility
Project leader: doc. RNDr. Flachbart Karol DrSc., akademik US Slovenska
Annotation:The aim of the mobility project is to prepare thin films of superconducting borides YB6 and ZrB12, and to investigate their properties as function of thickness, microstructure and applied pressure. The outcome of this investigation will be new information about how the superconducting properties of bulk (3D) superconductors change when they become two dimensional (2D). In this regard namely a modification of superconducting properties is expected due to a considerable change of rich phonon spectra in borides and of the related electron-phonon interaction, which are responsible for the origin of superconductivity. This research on borides is unexplored, therefore new and original results are expected. The project will, moreover, enable a mutual use of laboratory equipment (for thin film preparation in Leoben, for their investigation in Kosice), it will lead to promotion of post-docs and PhD students, to preparation of common publications, and probably also to further common projects.

Duration: 1. 1. 2021 - 31. 12. 2024
Program: VEGA
Project leader: RNDr. Jurčišin Marián PhD.
Annotation:Turbulent behavior belongs among basic properties of various macroscopic physical, chemical, biological, social-economical, financial, as well as environmental systems. Typical well-known examples of turbulent motions are various atmospheric phenomena (tornadoes, hurricanes, cyclones, etc.), turbulent streams in rivers and oceans, and turbulent motions in electrically conductive environments (motion of the outer earth core, solar wind, etc.) . The main task of theoretical investigations of turbulent systems is, first of all, the understanding of fundamental physical properties of turbulent flows that are common for all turbulent systems and which could potentially be applied in technical praxis in the future. In this respect, the main aim of the project is the investigation of the influence of breaking of various symmetries of developed turbulent environments on the properties of the anomalous scaling of correlation functions of fluctuating fields as well as on universal characteristics of turbulent systems.

Project leader: RNDr. Baťková Marianna PhD.
Annotation:The development of activities in the field of hydrogen technologies was also supported by the European Commission in the strategic document "Hydrogen Strategy for a Climate Neutral Europe". Today, Slovakia has suggested own national hydrogen strategy. Already in 2015, the National Hydrogen Association has founded to support research, implementation and use of hydrogen technologies. The Hydrogen Technology Center is being established in Košice with the main "Power-to-Gas" concept using renewable power energy sources with no negative impact on human life and without dependence on fossil fuels. A significant source of hydrogen is water and the electrolysis of water is the most promising technology for hydrogen production. However, before it can be recognized as an economically significant resource for large scale application with an exceptional energy potential, the simple, efficient, and secure methods of hydrogen retrieval have to be developed. For the time being, the most efficient electrocatalysts in terms of overpotential for hydrogen evolution reaction (HER) are noble metals. Unfortunately the high cost and scarcity of noble metals motivate the scientists to find the rival low-cost alternatives. Intrinsic structures of TMP meet the criteria of outstanding electrocatalysts that could further improve their HER performance in membrane electrode assembly. Excellent dispersity of electrocatalysts allows full use of active sites on catalysts to participate in electrode reaction to improve the electrocatalytic efficiency. Therefore, the main challenge in this project is to reduce the production cost of HER and at the same time to maintain the high efficiency of polymer electrode water electrolysis. Substantial aim of the project will be devoted to improve the PEM water electrolysis components mainly electrode materials based on modified carbon fibers electrocatalysts result in the technology which should be more approached to commercial markets.

ECODISC - Electron correlations in disordered superconductors

Program: APVV
Project leader: Mgr. Szabó Pavol CSc.
Annotation:Project aims at understanding of the effect of disorder on superconductivity in systems which are close to Superconductor-Insulator Transition as well as in thin films of hydrides. The thin films of MoN, MoC, TiN of various thickness and stoichiometry and on different substrates as well as polycrystalline and nanostructured boron-doped diamond will be prepared. Some of these systems reveal fermionic and some bosonic effects in superconducting state. By means of conductance measurements from DC to optical frequency range as well as by means of the scanning tunneling microscopy and spectroscopy at very low temperatures and in high magnetic field we will address the question of what kind of superconductivity is established in strongly disorderd systems where already quasiparticles out of superconducting state reveal renormalized density of states around the Fermi energy. We want also to understand the appearence of superconductivity in thin films of hydrides. We will explore the effect of disorder changing upon hydrogen content, thickness of film, substrate, microstructure and applied pressure on superconductivity in YHx, TiHx, VHx hydrides and their oxyhydrides.

FRUSTKOM - Frustrated metallic magnetic systems

Frustrované kovové magnetické systémy

Duration: 1. 8. 2018 - 30. 6. 2022
Program: APVV
Project leader: doc. RNDr. Gabáni Slavomír PhD.
Annotation:The up to now experimental and theoretical studies of frustrated magnetic systems (FMS) has been concentrated mainly on dielectric systems. Such systems can be found in 2D and 3D lattices based on equilateral triangles, and in dielectrics the interaction between their spins can be relatively well defined and described. In metallic FMS (M-FMS), which have been much less studied, an important role plays the long-range indirect exchange interaction between the spins mediated by conduction electrons (the RKKY interaction). To the small number of up to now studied M-FMS belong also some rare earth metallic borides having a fcc (e.g.HoB12, ErB12) or Shastry-Sutherland (e.g.TmB4, HoB4, ErB4) structure. This project aims are to investigate experimentally the impact of high pressure (hydrostatic and uniaxial), the influence of alloying and the anisotropy on the magnetic, transport and thermal properties of M - FMS, which has not been studied yet. A pioneering work will be above all the direct observation of magnetic structures of individual phase diagram regions of these M-FMS by spin-polarized scanning tunnelling microscopy. Investigated will be also the dynamics of magnetic structures (the influence of the rate of change of the magnetic field on these structures) and the study of magnetic excitations (by neutron diffraction methods) in selected tetraborides and dodecaborides. The challenging experimental studies, for which both high quality samples and suitable methods are already available, will be supported by the theoretical interpretation of received results, and by the theoretical elaboration.

Project leader: Ing. Koneracká Martina CSc.
Annotation:The presented project is focused on the preparation of a magnetic biocomplex that specifically detects cancer cells; it penetrates into their structure and enables better visualization of the affected areas, using magnetic resonance imaging (MRI), for example. The surface of synthetized magnetic nanoparticles will be functionalized by different amino acids. Several physicochemical methods (spectroscopic, microscopic, calorimetric, magnetic and others) will be used to optimize the nanoparticle functionalization. We will also study the suitability of using modified nanoparticles for MRI. The next step will be the conjugation of a specific antibody to the functionalized nanoparticles (biocomplex) and the study of cell interaction with biocomplex by immunochemical methods. Considering the application purposes of magnetic nanoparticles, one of our goals will be investigation the effect of prepared magnetic biocomplexes on cell viability in combination with magnetic hyperthermia.

Magnetic frustration and superconductivity in 2D and 3D borides

Magnetická frustrácia a supravodivosť v 2D a 3D boridoch

Duration: 1. 1. 2020 - 31. 12. 2023
Program: VEGA
Project leader: RNDr. Pristáš Gabriel PhD.
Annotation:Borides form a wide class of materials with different physical properties. Metallic geometrically frustrated magnetic tetraborides (REB4) are 2D frustrated systems and together with their fcc 3D counterparts dodecaborides (REB12) pose an ideal playground for study of 2D/3D interplay of frustration in megnetic systems. Uniaxial pressure, as well as hydrostatic pressure will be the tuning parameters which can change the interaction between magnetic moments. Depending on the direction of uniaxial pressure we will be able to change the magnitude of interactions in different crystallographic directions and test theoretical predictions. A similar crossover between 2D and 3D can be studied also in superconducting borides as YB6, ZrB12 and LuB12. Even if there exist at present time a rather good understanding of the physical properties of bulk metallic borides, there are still serious open questions what will happen if one dimension will be reduced considerably – by preparing thin films of corresponding borides.

Annotation:Structural changes of poly/peptides leading to the formation of amyloid aggregates are associated with incurable diseases, like Alzheimer's disease or diabetes. While the general mechanisms of fibril formation and their characterization are well reported, the early events during poly/peptide fibrillation are still unclear. The project is focused on understanding the early events mechanisms leading to the formation of pre-fibrillar (partially un/folded intermediates, nuclei, oligomers) and fibrillar amyloid aggregates of selected globular and intrinsically disordered proteins. Our focus will be the study of the kinetics of pre-fibrillar structures formation, their morphology, and cytotoxicity, under various experimental conditions, and in the presence of selected interacting partners (small molecules, nanoparticles). The obtained results will contribute to understanding the early events of amyloid aggregation and identifying the inhibitors with therapeutic potential for amyloid diseases.

PRESPEED - Perspective electronic spin systems for future quantum technologies

Perspektívne elektrónové spinové systémy pre budúce kvantové technológie

Duration: 1. 7. 2021 - 30. 6. 2025
Program: APVV
Project leader: RNDr. Vargová Hana PhD.
Annotation:The project is aimed at a comprehensive understanding of possibilities and limiting factors of electron spin systems for a quantum computation and quantum information processing, which will be investigated by the combination of advanced analytical and numerical methods including among others exact mapping transformations, localized-magnon theory, exact diagonalization, tensor-network methods, density functional theory, Monte Carlo simulations and density-matrix renormalization group method. In particular, we will examine the possibility to stabilize a bipartite and multipartite entanglement as a genuine quantum phenomenon needed for a quantum computation and quantum information processing at least up to temperature of liquid nitrogen or preferably room temperature. We will also explore the capability of the pulsed electron spin resonance for the spin-qubit manipulation. Quantum spin systems with topologically protected edge states eligible for a topological quantum computation will be investigated in detail together with a few selected quantum spin chains studied in connection with the implementation of a quantum teleportation. Frustrated Heisenberg spin systems supporting either the presence of a nontrivial skyrmion phase or magnon-crystal phases will be investigated in connection with the possibility to store a quantum information or to implement more complex quantum circuits. Heterostructures composed of atomically thin layers coupled by van der Waals forces will be examined with respect to a superconducting pairing and topological quantum computation. The studied electron spin systems will be either motivated by the effort to understand unconventional behavior of existing real magnetic materials or will be supplemented by the respective proposals for their experimental realization.

Self-organization processes in soft hybrid mixtures of liquid crystals and nanoparticles

Procesy samousporiadania v mäkkých hybridných zmesiach kvapalných kryštálov a nanočastíc

Duration: 1. 1. 2021 - 31. 12. 2024
Program: VEGA
Project leader: RNDr. Tomašovičová Natália CSc.
Annotation:The proposal aims to approach the research of liquid crystals doped with nanoparticles of different kind from a novel perspective of the self-organization that has an indisputable importance covering all fields of natural sciences, and has also a deep impact in social sciences. In such composite systems a subtle interplay among the nanoparticles, the self-assembling matrix and the topological defects commands the self-organization process. We will focus on the electric/magnetic field induced self-organization in such systems experimentally on different length scales by investigating the processes in different phases, isotropic, nematic, cholesteric with the anticipation that our results can be exploited in applications such as guided material transport, magnetic/electric switches/sensors, chemical/biosensors, in microfluidic/lab-on-a-chip devices, etc. We are convinced that systematic studies in this topic may change fundamentally current knowledge.

Rapidly quenched metallic alloys and composites for magnetic and magnetocaloric applications

Rýchlochladené kovové zliatiny a kompozity pre magnetické a magnetokalorické aplikácie

Duration: 1. 1. 2019 - 31. 12. 2022
Program: VEGA
Project leader: RNDr. Škorvánek Ivan CSc.
Annotation:The project addresses the development of novel rapidly quenched alloys with improved functional properties. Its first part will be focused on soft magnetic nanocrystalline alloys with high values of saturation magnetic inductions, which is possible to obtain by lowering of the content of non-magnetic elements in alloy and by utilization of the ultra-rapid annealing technique during the crystallization process. The other part of this project will be devoted to amorphous and nanocrystalline composites in the form of bilayer or trilayer ribbons, with the solid mechanical interface between them. In these heterogeneous systems, we will perform a detailed study of their magnetic properties. In addition, we plan also to optimize their GMI characteristics for potential magnetic sensor applications. In the project, we will focus our attention also on development of rapidly quenched composites with optimized magnetocaloric properties for magnetic cooling in the vicinity of room temperature.

Tear fluid and saliva in preventive, predictive and personalized medicine

Slzná tekutina a sliny v preventívnej, prediktívnej a personalizovanej medicíne

Duration: 1. 1. 2020 - 31. 12. 2022
Program: VEGA
Project leader: RNDr. Tomašovičová Natália CSc.
Annotation:Tear fluid and saliva are non-traditional biological collected material. Collection is non-invasive, which is an advantage compared to blood collection as a standard biological material. It is not colored, contains water and electrolytes, proteins, lipids, hormones and others. Characterization of its composition in various inflammatory diseases with a focus on amyloid formation by using several methods represents an approach of preventive, predictive and personalized medicine. Body fluid content in patients with pathological conditions varies significantly compared to healthy subjects. There are still unexplained interindividual changes in non-traditional body fluids in clinical-diagnostic practice, but these differences may allow personal diagnosis and application of tailor-made treatments.

Štruktúra a dynamika magnetických kvapalín v elektrickom poli

Duration: 1. 1. 2020 - 31. 12. 2023
Program: VEGA
Project leader: RNDr. Rajňák Michal PhD.
Annotation:Magnetic fluids (MF) are suspensions of magnetic nanoparticles (MNP) in a liquid carrier. Their behavior in magnetic field is intuitive and scientifically well explored. Within the fundamental research on MF, electrical properties of MF are actively studied, the clear understanding of which requires deeper experimental study. The mechanism of electrical breakdown and structural changes of MF in external electric field belong to the most intriguing properties of MF. The objective of this project is to investigate these phenomena experimentally in MF based on nonpolar liquids. Within the project, the streamer development will be visualized and investigated. The analysis will take into account the model of electric charge trapping on MNP. Dielectric spectroscopy, neutronography and microscopy of MF in electric field will be employed. The other objective is to prove or disprove a hypothesis of electromagnetic coupling between the spontaneous magnetic moment and induced electrical polarization of MNP.

Duration: 1. 1. 2022 - 31. 12. 2025
Program: VEGA
Project leader: RNDr. Farkašovský Pavol DrSc.
Annotation:The proposed project is devoted to the theoretical study of cooperative phenomena in strongly correlated electron and spin systems. The special attention will be paid to specifying the key mechanisms which lead to formation and stabilization of inhomogeneous charge and spin ordering, superconductivity, itinerant ferromagnetism, ferroelectric and magnetocaloric phenomenon due to the big application potential of these phenomena and their possible coexistence. The study will be performed on comprehensive model, which will take into account all relevant interactions in rare-earth and transition metal compounds, where besides the spin-independent Coulomb interaction in d and f band also the spin dependent (double exchange) interaction between both bands will be included. For a solution of this model we plan to elaborate new numerical methods, which will be subsequently used in combination with standard methods of quantum statistical physics (DMRG and QMC) to study the above mentioned phenomena.

Teoretické štúdium multifunkčných kvantových nízko-rozmerných magnetických materiálov

Duration: 1. 1. 2020 - 31. 12. 2023
Program: VEGA
Project leader: RNDr. Vargová Hana PhD.
Annotation:Multifunctional magnetic materials represent an ideal platform for nowadays technological demands. Reduced dimensions drag out their quantum properties opening thus new paradigms for possible utilization. The project aims to study exotic quantum states in low-dimensional magnetic materials. We plan to utilize first principles calculations based on density functional theory with the aim to propose and solve realistic effective quantum spin models for representative systems, which exhibit an enhanced magnetoelectric and/or barocaloric response in a vicinity of classical or quantum phase transitions. The present proposal focuses on frustrated quantum Heisenberg spin systems with flat bands appearing due to a destructive quantum interference, magnon-crystal phases (Wigner crystal of magnons) relevant for technological applications and one-dimensional quantum spin chains suitable for quantum information processing.

BMREBCO - Development of REBCO superconductors for biomedical applications

Vývoj REBCO supravodičov pre biomedicínske aplikácie

Duration: 1. 8. 2018 - 30. 6. 2022
Program: APVV
Project leader: Ing. Diko Pavel DrSc., akademik US Slovenska
Annotation:The project focuses on the development of REBCO bulk singlegrain superconductors (BSS) for biomedical applications. Their use is envisaged by the small enterprise CRYOSOFT s.r.o. Košice for design of equipments for the magnetic separation of cells and for the magnetic transport of drugs. For these applications, REBCO BSS will be developed for use at temperatures that can be achieved by cryocooling (30-50K). We will study YBCO, SmBCO and GdBCO systems that can meet the requirements for the expected applications. The raw material price for YBCO BSS is lower than for SmBCO and GdBCO BSS, however, the SmBCO and GdBCO are reaching higher values of trapped magnetic field. Within the project solution, the optimized composition and the preparation technology of REBCO BSS will be found in order to achieve efficient pining in high magnetic fields below temperature of liquid nitrogen, which is a prerequisite for achieving high critical current density and high trapped magnetic field. The critical current density will be improved through chemical pining, refining RE211 particles, adding nanofibers. We will take advantage of our previous results in basic and applied research of REBCO BSS, some of which are patent-protected.
