On the Theory of Magnetoelectric Coupling in Fe2Mo3O8/ M. Eremin, K. Vasin, A. Nurmukhametov // Materials. -2022. -V. 15. - P. 8229. |
Аннотация |
In the last decade, Fe2Mo3O8 was recognized for a giant magnetoelectric effect, the origin of which is still not clear. In the present paper, we contribute to the microscopic theory of the magnetoelectric coupling in this compound. Using crystal field theory and the molecular field
approximation, we calculated the low-lying energy spectrum for iron ions and their interaction with
electric and magnetic fields. Classical ionic contribution to the electric polarization related to the ionic
shifts is also estimated. It is found that the electronic and ionic contributions to the electric polarization
are comparable and these mechanisms support each other at T < TN. The suggested electronic
mechanism provides insight into the nature of huge jumps in polarization upon phase transitions
from paramagnetic (PM) to antiferromagnetic (AFM) and then to ferrimagnetic (FRM) states under
an applied external magnetic field as well as the large differential magnetoelectric coefficient. |
