Abstract
Abstract Cd doped Mn–Zn nanoferrites of the composition Mn 0.4 Zn 0.6 Cd x Fe 2− x O 4 , with (0.0≤ x ≤0.5) have been synthesized by a co-precipitation method. The X-ray diffraction patterns of the samples confirmed the formation of a single-phase cubic spinel structure. Average crystallite size is found to be in the range of 35–40 nm, which is in consistence with transmission electron microscopy results. The average grain size as calculated from scanning electron microscopy is found to be 100 nm. DC resistivity is found to be about 10 times higher than the reported values. Specific saturation magnetization is observed to be increasing from 25.23 emu/g to 48.93 emu/g with cadmium concentration. Magnetic moment is increasing from 1.07 BM to 2.35 BM with increasing concentration of Cd 2+ ions. Variation of anisotropy constant as a function of concentration of doping is also discussed. Comparatively higher DC resistivity, refined crystallite size and improved magnetization are the main achievements of the present investigation.
