摘要

Magnetoelectric composites, namely, xNiFe(2)O(4)+ (1-x)Ba0.9Sr0.1TiO3 were prepared by standard double sintering ceramic method. The X-ray diffraction analysis was carried out to check the phases formed during sintering and to calculate the lattice parameters. Scanning electron microscope (SEM) micrographs were taken to understand the microstructure of the samples. The dielectric constant (epsilon') and loss tangent (tan 6) were measured as a function of frequency in the frequency range 100 Hz-1 MHz. Variation of dielectric constant and loss tangent with temperature and composition has been reported. The hysteresis measurements were done to determine saturation magnetization (M-s) and coersivity (H-c). The variation of saturation magnetization and magnetic moment is interpreted in terms of composition. (C) 2007 Elsevier B.V. All rights reserved.
