Ramalho, L. Gama, S. Antonio, C. Paiva-Santos, E. Miola, R. Kiminami, A. Costa] Nickel ferrite powders with a nominal NiFe2O4 composition were synthesized by combustion reaction using urea as fuel. The powder was obtained using a vitreous silica basin heated directly on a hot plate at 480°C until self-ignition occurred. After combustion, the powder was calcined at 700°C for 2h. The formation of the spinel phase and the distribution of cations in the tetrahedral and octahedral sites of the crystal structure were investigated by the Rietveld method, using synchrotron X-ray diffraction data and Mössbauer spectroscopy. The material presented a crystallite size of 120nm and magnetic properties. The resulting stoichiometry after the Rietveld refinement was (Fe0.989(2) Ni0.011(2)) [Fe1.012(2) Ni0.989(2)] O4.
