Mn-doped BiFeO3 (BFMO) films were deposited on Pt(111), SrRuO3(SRO)/Pt(111) and LaNiO3(LNO)/Pt(111) bottom electrodes by radio-frequency (RF) sputtering. and -oriented BFMO films were formed on the SRO/Pt and LNO/Pt bottom electrodes, respectively. The remanent polarization (P r) in a -oriented BFMO film on the SRO/Pt bottom electrode was 80 µC/cm2, which was twice larger than that in a -oriented BFMO film on the LNO/Pt bottom electrode. However, the coercive field (E c) of the BFMO film on LNO/Pt bottom electrode (242 kV/cm) was much lower than that of the BFMO film on SRO/Pt (407 kV/cm). Furthermore, improved leakage current, breakdown field, and fatigue endurance characteristics were obtained in the -oriented BFMO film on LNO/Pt.
