Abstract
Multiferroic perovskites simultaneously exhibit ferroelectric, ferromagnetic, and/ antiferromagnetic ordering, as well as spontaneous polarization and magnetization controlled under magnetic and ferroelectric fields, simultaneously. There are many potential applications for multiferroic perovskites in the field of spintronics and magnetoelectric data storage. In the present investigation, we have synthesized and characterized the La-doped BiMnO3 ceramic material at high pressure and temperature by using solid state reaction route. The concentration of La into BiMnO3 at La site in the amount 0%, 2%, 4%, and 8% is fixed by the solid state reaction route and denoted by BML0, BML2, BML4 and BML8. Some impurity phases are observed by the powder X-ray diffraction analysis including the monoclinic structure for all compositions. Nevertheless, we encountered some difficulties while synthesizing BiMnO3 due to the volatile nature of Bi, antiferromagnetic behavior, large leakage current, etc. Enhanced dielectric properties are observed via the dielectric analysis. The reduction in the leakage current is observed with the La doping into BiMnO3.
