Coupling of spins with an electric field in FeV2 O4

Abstract

© 2019 American Physical Society. The microscopic mechanism of the interaction of exchange-coupled Fe and V spins in a FeV2O4 ferrimagnet with the electric field has been described. The derived effective energy operator makes it possible to calculate the electric polarization vector using the information about the magnetic structure. The calculated electric polarization is consistent with the available experimental data.
