Orthorhombic RMnO3 materials with a perovskite structure show functional properties associated e.g. with strong magneto-electric coupling (multiferroic materials) due to the great variability of structural parameters and the variety of types of magnetic arrangement in these materials. In the work "Matúš Mihalik, K. Csach, V. Kavečanský, Marian Mihalik: Cooperative Jahn-Teller effect in NdMn1-xFexO3+δ (0 ≤ x ≤ 0.2), Journal of Alloys and Compounds, 857 (2021) 157612" we showed the possibility of creating vacancies in the oxygen crystal positions, which opened the question to what extent the targeted variation of these vacancies will affect the functional properties associated with the magnetic arrangement.
