Direct magnetoelectric effect in three-layer Fe$_{0.45}$Co$_{0.45}$Zr$_{0.1}$–PbZr$_{0.53}$Ti$_{0.47}$O$_3$–Fe$_{0.45}$Co$_{0.45}$Zr$_{0.1}$ composites

Samples of three-layer amorphous ferromagnet-piezoelectric-amorphous ferromagnet composites with different thicknesses of the Fe$_{0.45}$Co$_{0.45}$Zr$_{0.1}$ layers have been fabricated by ion-beam sputtering of the Fe$_{0.45}$Co$_{0.45}$Zr$_{0.1}$ cast alloy on largest surfaces of the PbZr$_{0.53}$Ti$_{0.47}$O$_3$ piezoelectric plates prepared by ceramic technology. The influence of the alternating magnetic field frequency, thickness of ferromagnetic layers, constant magnetic field strength, and temperature on the specific features of the manifestation of the direct magnetoelectric effect has been investigated for the fabricated composites.
