Submicron-sized NiFe 2 O 4 particles were synthesized by the molten salt method at 900°C using binary melts of a NaCl and KCl mixture that acts as a flux. The X-ray diffraction pattern confirmed the single phase, high crystalline and cubic structure of NiFe 2 O 4 with a Fd3m space group. The FT-IR spectra reveal the stretching vibration of octahedral complexes of Fe...
