Description Bismuth ferrite thin films with 10% La and 5% Mn (BLFMO) have been deposited using Pulsed laser deposition. It is found that oxygen pressure has pronounced effect on the structural and electrical properties of BLFMO thin films. The leakage current density increases with the oxygen pressure. At 0.007 mbar, the leakage current density is found to be in the order of 10(-7)A/cm(2) at 200kV/cm. The remnant polarization is 73C/cm(2) at 200kV/cm. Fatigue endurance has been studied for optimized film and found that films are almost fatigue free after 10(8) pulses. There is only 3% change in the polarization up to 10(6) seconds as revealed by retention test.
