Magnetoelectric effect in hybrid structures metal-magnetoelectric-metal

To increase magnetoelectric conversion, composite magnetoelectric structures based on a bulk magnetoelectric composite lead zirconate-titanate: nickel ferrite, on which layers of nickel and alternating layers of nickel-cobalt are deposited on both sides by electrochemical deposition, were obtained for the first time. The field dependences of the linear low-frequency magnetoelectric effect of the resulting structures have been studied. It is shown that in hybrid structures the value of the magnetoelectric coefficient is one and a half times greater than its value compared to bulk samples of the same composition. In addition, its maximum shifts to the region of weaker fields for both longitudinal and transverse orientations of the magnetic field.
