Theory of magnetoelectric phenomena in composites

V.M. Petrov     Novgorod State University, Veliky Novgorod, Russia

Abstract

The chapter discusses the theoretical modeling of magnetoelectric (ME) coupling in composites of magnetostrictive and piezoelectric components. Our analysis is based on the simultaneous solution of elastodynamic or elastostatic and electro/magnetostatic equations. The expressions for ME coefficients as functions of initial component parameters are obtained for low-frequency, electromechanical, magnetic, and magnetoacoustic resonance regions. The obtained models are exemplified by representative compositions. A theory for the resonance enhancement of ME interactions at frequencies corresponding to electromechanical resonance ...
