Enhancement of the magnetoelastic and magnetoelectric interaction in antiferroelectric antiferromagnets

Influence of Mechanical Pressure and External Field on Dynamic Interactions in Segnetomagnetics

“…In the magnetic part of the Hamiltonian HM homogeneous and inhomogeneous exchange energy, anisotropy energy, and Zeeman energy are taken into consideration [1]. In the ferroelectric part of the Hamiltonian HF we take into account the contribution from the exchange interactions, anisotropy, and an external electric field E=E(0,y,0) [4][5].…”
