Nano-structured NiCuZn ferrite with composition NixCu0.1Zn0.9-x (where x = 0.0, 0.2, 0.4, 0.6) was prepared by self propagating technique. X-ray diffraction (XRD) patterns of all samples exhibited the spinel structure. Further, the XRD data have been applied to calculate the lattice parameter and grain size. The structural probes and nanometric sizes of the samples was examined by using scanning electron microscopic techniques. Dielectric constant varied from 30 to 80,000 with frequency, rise in Ni concentration and temperature. Vibrating Sample Magnetometry (VSM) was employed to study the magnetic properties of nano-ferrite. High saturation magnetization of value 62.3 emu/g was measured for the sample consisting Ni concentration X= 0.6. These nano-ferrites may have application in core materials and in electronic device technology.
