We have successfully grown ferroelectric Pb-0.92 La0.08Zr0.52Ti0.48O3 (PLZT) films on base metal foils by chemical solution deposition using sol-gel solutions containing polyvinylpyrrolidone. Under zero-bias field, we measured a dielectric constant of approximate to 820 and dielectric loss of approximate to 0.06 at room temperature, and a dielectric constant of approximate to 1250 and dielectric loss of approximate to 0.03 at 150 degrees C. In addition, leakage current density of approximate to 1.5 x 10(-8) A/cm(2), remanent polarization of approximate to 11.2 mu C/cm(2), and coercive field of approximate to 40.6 kV/cm were measured at room temperature on a approximate to 3-mu m-thick PLZT film grown on LaNiO3-buffered nickel substrate. Finally, energy density approximate to 25 J/cm(3) was measured from the P-E hysteresis loop at an applied field of 2 x 10(6) V/cm.
