Abstract

Abstract: A structurally correlated magnetization enhancement is reported for Mn doped 0.9BiFeO3 –0.1BaTiO3 compounds. X-ray diffraction and Rietveld refinement studies revealed a distorted perovskite structure with the coexistence of rhombohedral and monoclinic symmetries. Mössbauer spectroscopy results showed a magnetic spectral signature of ordered Fe 3 + ions for the rhombohedral phase of the undoped sample, and for both rhombohedral and monoclinic phases of the Mn doped samples. A significant magnetization increase (reaching 0.50 emu/g), associated to the magnetic ordering of the Cm phase and to the retention of the Mn 3 + valence state, was observed for Mn doped samples.
