摘要：

The observation of magnetoelectric coupling is reported in (x) Ni0.8Cu0.2Fe2O4 + (1 - x) Ba0.5Pb0.5Ti0.5Zr0.5O3 composites synthesized by normal solid state reaction method. The phase formation was confirmed by X-ray diffraction technique and no intermediate or impurity phase is present in all the composites. The dielectric constant (epsilon') and dielectric loss (tan delta) were measured as a function of frequency and temperature. The dielectric constant was found to be enhanced with increase in ferrite content in the composite. It was also revealed that magnetoelectric output decreases with increase in ferrite content in the composite due to leakage current. The maximum voltage coefficient of 0.411 mV/cm/Oe was observed in 15% Ni0.8Cu0.2Fe2O4 + 85% Ba0.5Pb0.5Ti0.5Zr0.5O3 composite.
