Abstract

An Mn substituted cobalt ferrite system was prepared using a simple, low temperature auto-combustion method followed by heating at 600 °C for 3 h. In this method, the thermochemical decomposition of amino acids such as glycine at elevated temperatures in the presence of salt nitrates, especially iron nitrate, produced a ferrite system. The as-prepared Mn-Co ferrite was characterized by XRD, SEM, IR and EDX techniques. These techniques revealed that the employed preparation method led to formation of a single phase of nanocrystalline spinel Mn0.5Co0.5Fe2O4 powder. However, various structural and morphological properties of the as-synthesized ferrite were determined. Porous and agglomerated morphology of the bulk sample was displayed in the scanning electron microscopy image. The VSM technique displayed the saturation magnetism of Mn0.5Co0.5Fe2O4 as 51.53 emu/g.
