The effect of doping on the magnetoelectric (ME) properties of Pb(Zr 0.52Ti0.48)O3-Ni(1-x)Zn xFe2O4 composites was investigated in order to understand the compositional dependence of the ME coefficient. Doping of Ni ferrite was done in order to improve the resistivity, permeability, magnetization and coercive field, and the addition of Zn to the ferrite structure increases the resistivity, permeability, and magnetization, but it reduces its Curie temperature. The advantage of using Ni-based ferrite, over Mn-ferrite, is that it has a higher electric resistivity and lower dielectric loss. Experimental investigation showed that nickel-based ferrite particles are very stable in a doped-PZT matrix and do not react even at high sintering temperatures of 1,250 °C.
