Magnonics is an emerging field of science in nanomagnetism that deals with spin waves to transmit, store and information processing. Magnons are the quanta associated with spin waves. They carry information about the collective spin behavior, while they can be modulated through a suitable arrangement of magnetic structures in combination with an external electric and magnetic field. Potential use includes a wide range of applications such as RF components (reconfigurable filters, delay lines), multiplexers, interference-based logic gates, unconventional spin-wave computing, and neuromorphic and quantum computing.
The work will be focused on designing a suitable shape and arrangement of magnetic nanoelements and also on optimizing their preparation. Electron-beam lithography in combination with other microfabrication technologies such as deposition and etching of metallic layers will be used for their preparation. Process optimization also includes characterization of structures using scanning techniques such as SEM and AFM. The prepared structures will be then studied using various techniques, mainly using a magnetic force microscope.
