摘要：

The phase structure, microstructure, piezoelectric properties, dielectric characteristic and the ME effect of magnetoelectric Pb[Zr0.23Ti0.36+0.02(Mg1/2W1/2)+0.39(Ni1/3Nb2/3)]O-3 (PZT)+xNi(0.8)Co(0.1)Cu(0.1)Fe(2)O(4) (NCCF) composite ceramics were prepared by the conventional solid state reaction method. The structural analysis of both the constituent phases and their composites was carried out by X-ray diffraction, energy dispersive spectrometry and scanning electron microscopy. The results showed cubic spinel structure for ferrite phase and tetragonal perovskite structure for ferroelectric phase. The piezoelectric constant, dielectric constant, Curie temperature, remanent polarization and coercive electric field decreased with increase of ferrite content. The coercive field strength, saturation magnetization and remanent magnetization increased with increasing ferrite content. (C) 2011 Elsevier B.V. All rights reserved.
