Specific features of the inverse magnetoelectric effect in two-layered Tb0.12Dy0.2Fe0.68-PbZr0.53Ti0.47O3 composites

The two-layered Tb_0.12Dy_0.2Fe_0.68-PbZr_0.53Ti_0.47O₃ magnetoelectric composites have been prepared by the deposition of ferromagnetic layers of different thicknesses from a thoroughly mixed Tb_0.12Dy_0.2Fe_0.68 ferromagnetic powder and an epoxy glue on preliminarily polarized PbZr_0.53Ti_0.47O₃ piezoelectric layers. The dependences of the inverse magnetoelectric effect on the frequency and strength of an electric field, the strength of a constant magnetic field, the thickness of a ferromagnetic layer, the average size of Tb_0.12Dy_0.2Fe_0.68 grains in the ferromagnetic layer, and the temperature have been determined. Conditions for the maximum magnetoelectric response have been established.
