成果简介：Pure BiFeO3 (BFO) and Cr-doped BiFe0.97Cr0.03O3 (BFCO) thin films were successfully prepared on F-doped SnO2 conductive film (FTO)/glass (SnO2: F) substrates by a sol-gel method. The improved ferroelectricity with remnant polarization (Pr) of about 2Pr = 68.68 μC/cm2 under an applied electric field of 1,181.8 kV/cm and enhanced ferromagnetism with saturation magnetization (Ms) of Ms = 0.93 emu/cm3 have been observed in the BFCO thin film. The improved electrical properties of the BFCO thin film are ascribed to the coexistence of trigonal and tetragonal phase and high valence of Cr6+, and the Fe-O6 octahedron distortion is enhanced due to the overlap and hybridization of Fe3d/Cr3d and O 2p orbits by Cr doping.
