Abstract
A theory of the magnetoelectric (ME) effect in a ferromagnetic-piezoelectric bilayer structure is presented. An expression for the ME voltage coefficient in terms of the parameters of the ferromagnetic and piezoelectric phases is obtained, and the dependence of this coefficient on the frequency and the ratio of the ferromagnetic and piezoelectric layer thicknesses is analyzed. The results of numerical calculations of the ME voltage coefficient for a permendur-PZT bilayer system are in satisfactory agreement with experimental data.
