Abstract
A theory of the magnetoelectric (ME) effect in a multilayer ferrite-piezoelectric hybrid composite is presented. Proceeding from the material equations and the equations of motion, an expression for the frequency dependence of the ME voltage coefficient is obtained which involves the parameters of the ferrite and piezoelectric phases. In the region of the electromechanical resonance of the composite, the ME voltage coefficient exhibits a sharp increase. The results of calculations for a Terfenol-D-PZT hybrid composite are in satisfactory agreement with experimental data.
