Аннотация

Measurements of the direct magnetoelectric effect with respect to voltage are performed for threelayer structures of multiferroic composites. In the region of 83.6 kHz, corresponding to the resonance frequency, an anomalous increase in the magnetoelectric effect is observed for all samples. The maximum effect value is 22 mV/(cm Oe) for a Ni–PZT–Pt sample with a nickel layer 1.8 μm in thickness, which is a good indicator, considering that the bias field was zero. The anomalies of the magnetoelectric effect are of a nonlinear nature, as they depend on the thickness and technology of deposition of the magnetostrictive layers.
