The local distortion and electronic behavior in Mn doped BiFeO3

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.
