摘要：

Nickel-zinc ferrites having the chemical formula Ni1-xZn2Fe2O4 for x ranging from 0.0 to 1.0 with the step increment of 0.2 have been prepared by the standard solid state reaction technique. X-ray powder diffraction patterns confirm the spinet structure for the prepared compounds. Lattice parameters increase from 8.337 to 8.490 angstrom and DC electrical resistivity varied from 1.629 x 10(6) to 0.003 x 10(6) Omega cm with the rise of x. Dielectric constant changed from 1,465,600 to 13 with the variation of frequency from 80 Hz to 1 MHz, respectively. All the samples follow the Maxwell-Wagner's interfacial polarization. The effect of density related and DC electrical properties are undertaken in terms of concentration of zinc. (c) 2007 Elsevier B.V. All rights reserved.
