Multiferroic and optical studies on the effects of Ba2+ ions in BiFeO3 nanoparticles

Single phase Ba2+ ions doped BiFeO3 nanoparticles have been successfully synthesized with varied concentration (0.0 ≤ x ≤ 0.2) using the auto combustion method. The structural properties of Bi1−xBaxFeO3 (x-0.0, 0.1 and 0.2) nanoparticles reveal the formation of highly crystalline rhombohedrally distorted perovskites without undergoing any structural phase transformation analyzed via Rietveld refinement. The Pauling’s equation confirmed that Ba2+...
