Abstract

The mixed spinel ferrite system Mg_0.95Mn_0.05Fe_2−2xTi_2xO₄ (0⩽x⩽0.7) was synthesized by the conventional solid-state reaction technique. The effect of Ti⁴⁺ doping was studied by using the Mössbauer spectroscopy measurements at room temperature. From the analysis of the Mössbauer spectra, it is observed that s-electron density, electric field gradient (EFG), quadrupole coupling constant (QCC) and the net hyperfine magnetic fields acting on the Mössbauer nuclei-Fe_A³⁺ and Fe_B³⁺ change with the increase of Ti⁴⁺ doping in Mg_0.95Mn_0.05Fe₂O₄. The hyperfine magnetic field decreases with the increase of Ti⁴⁺ doping.
