摘要

Nanocrystalline forms of nickel ferrite (NiFe 2 O 4 ) have been synthesized with the aid of single step chemical combustion method using citric acid as fuel in the 1:1 ratio. The single phase formation of nickel ferrite was confirmed through powder X-ray diffraction (XRD). The presence of various functional groups was confirmed through Fourier transform infrared spectroscopic (FTIR) analysis and the compositional analysis was performed through Energy dispersive X-ray studies (EDX). The micro structural features of nanocrystallites were examined by scanning electron microscope (SEM). Surface morphology of the nanocrystalline form of NiFe 2 O 4 was also investigated through transmission electron microscopic (TEM) analysis. Magnetic measurements have showed the ferrimagnetic properties with Curie temperature @ 500 °C. The obtained results are in good agreement with the reported values. The other results have been discussed in detail.
