Inverse magnetoelectric effect in Pb(Zr,Ti)O3 (PZT) / Finemet two-layered composite structures

In recent years, much attention has been paid to the study of magnetoelectric (ME) effects in solids that was caused by the possibility of their practical applications. In most of natural crystals, ME effects are small in magnitude and are observed, as a rule, at low temperatures or in large magnetic fields. To date, most of the experimental work is devoted to a direct magnetoelectric effect. However, the study of the inverse magnetoelectric effect also deserves attention. The ME effect can be increased by creating composite structures. This paper is devoted to the study of the reverse ME effect in a two-layer composite sample consisting of a piezoelectric plate Pb(Zr, Ti) O3 and an amorphous FeSiBNbCu ferromagnetic ribbon. It was found that the ME effect depends on the magnitude of the magnetization reversal field, H, the electric voltage, U, and also on their mutual orientations.
