摘要：

The mixed spinel ferrite system Mg0.95Mn0.05Fe2-2xTi2xO4 (0 <= x <= 0.7) was synthesized by the conventional solid-state reaction technique. The effect of Ti4+ doping was studied by using the Mossbauer spectroscopy measurements at room temperature. From the analysis of the Mossbauer 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 Mossbauer nuclei-Fe-A(3+) and Fe-B(3+) change with the increase of Ti4+ doping in Mg0.95Mn0.05Fe2O4. The hyperfine magnetic field decreases with the increase of Ti4+ doping.
