Abstract

Nickel–zinc ferrites having the chemical formula Ni1−xZnxFe2O4 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 spinel structure for the prepared compounds. Lattice parameters increase from 8.337 to 8.490 Å and DC electrical resistivity varied from 1.629 × 106 to 0.003 × 106 Ω 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.
