The magnetoelectric (ME) composites consisting of ferrite and ferroelectric phases viz. (y) Ni 0.8 Zn 0.2 Fe 2 O 4 +(1−y) PbZr 0.52 Ti 0.48 O 3 (PZT) in which y varies as 0, 0.15, 0.30, 0.45 and 1mol% were prepared by a conventional double-sintering ceramic method. The presence of two phases in composites was confirmed by XRD technique. The variation of dielectric constant (έ) and loss tangent (tanδ) with frequency in the range 20Hz–1MHz at room temperature and also with temperature at four different frequencies (viz.1kHz, 10kHz, 100kHz, and 1MHz) were studied. The detailed studies on the dielectric properties were done presuming that the magnetoelectric interaction between constituent ferrite and ferroelectric phases may result in various anomalies in the dielectric behaviour of these composites. Ac conductivity measurements were carried out to determine the nature of charge carriers during conduction. The value of static magnetoelectric conversion factor (dE/dH) H was measured as a function of intensity of applied dc magnetic field. The maximum value of ME voltage coefficient viz. 769μVcm −1 Oe was observed for a 15% Ni 0.8 Zn 0.2 Fe 2 O 4 +85% PZT composite.
