Abstract
Bi0.95La0.05FeO3(BLFOx=0.05) film was fabricated on indium tin oxide/glass substrate using a metal organic decomposition method. No secondary phase can be observed in the well crystallized and predominantly (110)-oriented BLFOx=0.05 film. Well-saturated P - E hysteresis loops with the remanent polarization of 60.7 μC/cm2 can be obtained in BLFOx=0.05 film due to the low leakage currents as well as the preferred orientation of the (110) peak. The content of oxygen vacancies in the film is considered to be the dominant factor affecting the asymmetry ferroelectric properties and leakage currents.
