The nanocrystalline Mg1-xMnxCr2O4 (X=0.0, 0.25, 0.50, 0.75 and 1.0) chromite were synthesized by sol-gel autocombution route. Thermal analysis of precursor after autocombution was carried out by TG-DTA. X-ray diffraction confirmed the formation of single cubic spinel lattice for all compositions. Lattice parameter shows increasing trend with an increase in Mn content. Formation of spherical nanoparticals were revealed by scanning electron microscopy (SEM).The elemental analysis obtained by EDAX is in close agreement with the expected composition from the stoichiometry of reactant used. The magnetic data indicate that, all compositions are ferrimagnetic in nature. The detailed results of XRD, thermal analysis, SEM, EDAX and magnetic properties indicating the role of substitution of manganese metal ions on the structural and magnetic properties of magnesium chromites are presented.
