| Abstract: | Ce substituted Bi1−xCexFeO3 (BCFO) films with x=0–0.15 were deposited on indium tin oxide (ITO)/glass substrates by sol–gel process annealed at 500 °C. Rhombohedral phase was confirmed by XRD study and no impure phases were observed till x=0.15. Substantially enhanced ferroelectricity was observed at room temperature due to the substitution of Ce. In the films with x=0.05 and 0.10, the double remnant polarization are 75.5 and 57.7 μC/cm2 at an applied field 860 kV/cm. Moreover, the breakdown field was enhanced in the films with Ce substitution. |
