Abstract: Pure nickel ferrite (NiFe2O4) and magnesium substituted nickel ferrite (Ni1-xMgxFe2O4) with particles size in Nano-meter range were synthesized by using auto combustion technique. In this study, it has been observed that with increase in sintering temperature, the estimated bulk density of the materials increases. The XRD patterns of the samples show the formation of single phase materials and the lattice parameters estimated using XRD patterns. FT-IR spectra shows two small peaks in the band region 400-1000 cm-1 (vibrational) and another peaks in the band range 1000- 4000 cm-1 in all the samples, characteristics of spinel structure. From Raman spectra, the Raman shift of pure NiFe2O4 and MgxNi1-xFe2O4 are comparable with the experimental values reported in literature. The Raman spectra gives five Raman active modes (A1g + Eg + 3F2g) which are expected in the spinel structure.
