Manganese ferrite nano-particles are synthesised by combustion route by using a mixture of glycine and ammonium nitrate as fuels with corresponding metal nitrates. The nano-sized Mn ferrite characterized by X-ray diffraction (XRD), Scanning electron micrographs (SEM) and Energy dispersive X-ray (EDX) techniques. When the mixture of glycine and ammonium nitrate is used, moderate crystalline MnFe2O4 is obtained as a single phase with irregular shape. Both the saturation magnetization (80 emu/g) and the remnant magnetization (50 emu/g) were found to be highly depending upon the size and crystallinity of the investigated ferrite. Our results indicate that this method might provide a promising option for synthesizing high-quality nano-sized MnFe2O4 which has the same saturation magnetization value of bulk Mn ferrite.
