Abstract

We investigated the effects of In3+ and Co2+ substitutions on the structural and magnetic properties of Mg-Mn ferrites. The cation distribution technique was taken into account to estimate the magnetic interactions. Cation distribution was also used to investigate the ionic radii of tetrahedral and octahedral sites, oxygen positional parameter, site bond as well as edge lengths, bond lengths and bond angles. The ionic radius of tetrahedral site and octahedral site was observed to increase with the incorporation of In3+ and Co2+ ions respectively. Theoretical lattice parameter was observed to increase with the substitution of In3+ and Co2+ ions. In3+ substitution resulted in weakening of super-exchange interactions while in Co2+ substituted Mg-Mn ferrites, anisotropy was observed to play a decisive role in addition to bond lengths and bond angles.

Keywords
