Abstract

BiFeO₃-based ceramics have been fabricated by the solid state reaction. The effect of BaTiO₃ content in BiFeO₃-BaTiO₃ system on the crystal structure, the magnetic properties and the electrical properties were investigated. Perovskite BiFeO₃ was stabilized through the formation of solid solution with BaTiO₃. Rhombohedrally distorted BiFeO₃-BaTiO₃ showed weak ferromagnetism. Furthermore, the dielectric properties of resultant ceramics was greatly improved by a small amount of Mn doping.
