Enhanced ferromagnetism and weak polarization of multiferroic BiFeO3 synthesized by sol-gel auto-combustion method
BiFeO3 nanoparticles and ceramics were prepared by sol-gel auto-combustion method. Optimal conditions for the synthesis of pure BiFeO3 nanoparticles were experimentally obtained by X-ray diffraction patterns analysis. Scanning electronic microscope was used to investigate microstructure [...]
