Abstract

Pure and 5 at%-Cr, Mn, Co, Ni or Cu added BiFeO3 films were fabricated on 111-textured Pt/Ti/SiO2/Si(100) substrates by chemical solution deposition followed by annealing at 773K, and their crystal structure, microstructure and electrical properties were investigated. Cr and Ni are not attractive as additives because the Cr added film was crystallized into an undesirable phase and the Ni added film was amorphous and/or low crystallinity. The Co added film showed unsaturated hysteresis loops due to high coercive field. The Cu addition improved the shape of hysteresis loops as well as the Mn addition which suggested the decrease of leakage current at high applied field although the surface morphologies of these films were quite different.
