Role of Substituting Manganese for Iron Cations in Changes of the Magnetic and Electrical Characteristics of BiFe1 − xMnxO3 Magnetoelectrics (x = 0.05 and 0.15)

In contrast to BiFeO 3 , samples of BiFe 1  − x Mn x O 3 solid solution ( x = 0.05 and 0.15) are ferromagnets and semiconductors. Raising x lowers the Curie temperature ( T C = 605 K when x = 0.05 and 550 K when x = 0.15) and increases dielectric permittivity ε at room temperature. The drop in the v...

Description
Summary:In contrast to BiFeO 3 , samples of BiFe 1  − x Mn x O 3 solid solution ( x = 0.05 and 0.15) are ferromagnets and semiconductors. Raising x lowers the Curie temperature ( T C = 605 K when x = 0.05 and 550 K when x = 0.15) and increases dielectric permittivity ε at room temperature. The drop in the value of specific magnetization as x rises is due to redistribution of the volumes of ferromagnetic and antiferromagnetic phases.
