Piezoelectric-magnetostrictive (magnetoelectric) composites using piezoelectric lead zirconate titanate (PZT) ceramic and magnetostrictive Ni-Zn ferrite (NZF) with compositional formulae (1-x) PbZr0.65Ti0.35O3-x Ni0.8Zn0.2Fe2O4 with x = 0 to 0.15 in steps of 0.05, were prepared by a conventional solid state route. The presence of individual phases was confirmed using X-ray diffraction. Dielectric properties were studied as a function of temperature and frequency presuming that the interactions between the piezoelectric and magnetostrictive phases may result in various anomalies in the dielectric properties of these composites. To study the ferroelectric properties, P-E hysteresis loops were recorded.
