Ba and Mn co-Doped Bismuth Ferrite (BiFeO3) Nanoparticles: Tailoring the Multiferroic Features Through Phase Transformation — •Astita Dubey, Marianela Escobar, Vladimir V. Shvartsman, and Doru C.

Multiferroic Bismuth Ferrite (BiFeO3; BFO) Nanoparticles (NPs) are noteworthy suitable materials for spintronics and memory devices due to their advantageous ferroelectromagnetic properties at room temperature. The research on BFO NPs is getting much attention due to enormous magnetic and photocatalytic behavior than their bulk counterparts. We reported systematic study of phase transition and impact on the multiferroic properties due to doping of Ba and Mn in pristine BFO NPs (BixBa1-xFeyMn1-yO3). Crystalline doped NPs sized 30-50 nm exhibit higher crystallographic symmetry from rhombohedral (R3c) to orthorhombic (Pbnm) with enhanced size induced magnetization as well as decrement in impure phases. All NPs were synthesized by wet chemical route (modified sol-gel and hydrothermal) and characterized via UV-VIS absorption spectroscopy, XRD diffraction, TEM, EDX, SEM, Impedance dielectric spectroscopy and Magnetic force microscopy.
