摘要：Significant perturbation on the local magnetic structure and related behavior in BiFeO3 is achieved through a substitution of Fe by Mn. The BiFe1-xMnxO3 ceramics were synthesized by sol-gel method and self-sustaining combustion. The crystal structure of BiFe1-xMnxO3 (0 <= x <= 0.3) changes from rhombohedral R3c to ortho-rhombic Pbnm forming a biphasic region at 0.05 <= x <= 0.15. It is found that the phase fraction change can effectively regulate the macroscopic magnetization and magnetoelectric coupling. The amount of the R3c phase reduces significantly with the Mn content increasing. The ceramic consisting of two phases with almost equal fractions shows a remnant magnetization and magnetoelectric coupling coefficient of 0.40 emu/g and 7.65 mV/(cm.Oe), respectively.
