Abstract

It is expected that BiFeO3-based materials will have both ferroelectricity and ferromagnetism. (1-y)BiFe(1-x)MnxO3-yBaTiO3 system was prepared using solid state reaction method. The goal of this study is to uncover the impacts of Mn doping and BaTiO3 content on the crystal structure, magnetism and ferroelectric properties. By forming a solid solution with BaTiO3, stable perovskite BiFeO3 was achieved. The rhombohedrally distorted (1-y)BiFe(1-x)MnxO3-yBaTiO3 showed weak ferromagnetism due to the composition of BaTiO3 and the doping of Mn ion. 0.8BiFe0.9Mn0.1O3-0.2BaTiO3 and 0.7BiFe0.9Mn0.1O3-0.3BaTiO3 ceramics exhibited typical P-E hysteresis loops.
