The samples of BiFe1 – xMnxO3 solid solution system (x = 0.05 and 0.15) are ferromagnetics and semiconductors unlike BiFeO3. Growth of x leads to a decrease in Curie temperature (TC = 605 K for x = 0.05 and 550 K for x = 0.15) and growth of dielectric permittivity ε at room temperature. The decrease in the value of specific magnetization with increasing x is due to the redistribution of the volumes of ferromagnetic and antiferromagnetic phases.
