Direct magnetoelectric effect in bilayered ceramic composites based on Mn$_{0.4}$Zn$_{0.6}$Fe$_{2}$O$_{4}$ ferrimagnet and PbZr$_{0.53}$Ti$_{0.47}$O$_{3}$ ferroelectric
Abstract:
Under different experimental conditions, the direct magnetoelectric effect was studied in two-layer composites prepared both by joint sintering of layers of powders of ferrimagnet Mn$_{0.4}$Zn$_{0.6}$Fe$_{2}$O$_{4}$ and ferroelectric PbZr$_{0.53}$Ti$_{0.47}$O$_{3}$ and by gluing plates pre-sintered from powder materials of Mn$_{0.4}$Zn$_{0.6}$Fe$_{2}$O$_{4}$ and PbZr$_{0.53}$Ti$_{0.47}$O$_{3}$. It was found that sintered composites show greater values of the magnetoelectric effect than composites prepared by gluing sintered plates together. The revealed regularities are in good agreement with the conclusions from the theoreti-cal model of the effective parameters of the heterogeneous environment.
