Modeling Magnetoelectric Multiferroics

Abstract

The article dwells on the theoretical modeling of magnetoelectric (ME) effect in multiferroics based on magnetostrictive and piezoelectric materials. The analysis is based on the simultaneous solution of elastodynamic or elastostatic and electro/magnetostatic equations. The expressions for ME coefficients as a function of the material parameters and volume fractions of components are presented. Longitudinal, transverse, and in‐plane cases are considered. The models presented adequately describe the ME effect in ferrite cobalt–barium titanate, ferrite cobalt–PZT, ferrite nickel–PZT, and lanthanum strontium manganite–PZT composites.
