Abstract: Magnetoelectric composites of (x) Ni0.5 Zn0..5 Fe2O4 [NZFO]+(1-x) PLZT in which x varies as 0, 0.15, 0.30 and 1 were prepared by solid-state reaction technique. The presence of single phase in x = 0 and x = 1 as well as two phases in x = 0.15, 0.30 and 0.45 composites was confirmed by X-Ray Diffraction (XRD) technique. Scanning electron microscopy was employed for micro-structural studied. The variation of dielectric constant (ε') with frequency (100-5 MHz) has been also studied. The static Magnetoelectric (ME) voltage coefficient was measured as function of applied DC magnetic field and variation in ME response has been explained in terms of the contents of piezomagnetic phase and intensity of applied magnetic field. The maximum ME conversion factor of 6.26 mV/cm.Oe was observed for 15% NZFO+85% PLZT composite.
