Magnetoelectric coupling in noncollinear ferrimagnets

Abstract

© Kazan Federal University (KFU). The analytical expressions for the energy coupling of exchange coupled spins with electric field, induced by odd crystal field has been derived in the third order perturbation theory, combining the action of electric field, spin-orbit and exchange interactions. The magnetoelectric coupling due to the partial replacement of the Cu2+ positions by Li+ in LiCuVO4 has been discussed.
