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.
