Nanostructured Mn-Ni-Zn ferrite with composition Mn0.1Ni0.6Zn0.3InxFe (2-x) O4 ( x =0.05, 0.1, 0.15, 0.2) was prepared by sol-gel method. X-ray diffraction (XRD) patterns of all samples showed the spinel structure. The dielectric permeability, AC resistivity and DC resistivity was measured and it was observed that the sample with x = 0.1 has highest resistivity. Vibrating Sample Magnetometry (VSM) is used to characterize the magnetic properties of prepared nanoferrites. The maximum saturation magnetization (36.2 emu/g) was observed for the sample with x = 0.1. For the same sample the coercivity was found very small (7 Oe). These materials are expected to have applications in core material and in electronic devices technology.
