Fatigue-free Bi3.25La0.75Ti3O12 (BLT) thin films were grown on LaNiO3,RuO2, and La0.5Sr0.5CoO3 bottom electrodes in a microwave furnace at 700 °C for 10 min. The remanent polarization (Pr) and the drive voltage (Vc) were in the range of 11–23 μC/cm2 and 0.86–1.56 V, respectively, and are better than the values found in the literature. The BLT capacitors did not show any significant fatigue up to 1010 read/write switching cycles.
