Mn substitution provides perfect perturbation on the local structure and electronic behavior of BiFeO3. The crystal structure of BiFe1-xMnxO3 (0 <= x <= 0.3) changes from rhombohedral R3c to orthorhombic Pbnm via a biphasic region with increasing x. It is found that Mn doping leads to the depolarization of the Bi-O configuration, and the Jahn-Teller distortion of Fe/MnO6 octahedra. An enhancement of remanent magnetization of BiFe1-xMnxO3 is observed. (C) 2015 Elsevier B.V. All rights reserved.
