Abstract

The perovskite oxide YBa2Cu3O7-X (YBCO) and Pb(ZrXTi1-X)O3 (PZT) thin films have been deposited for superconducting-ferroelectric devices. KrF excimer laser ablation technique was used at the deposition conditions of 200-600 m Torr O2, 2-3 J/cm2 and 5-10 Hz operation frequency. Heterostructures of PZT-YBCO-YAlO3:Nd show the zero resistivity critical temperature of 82 K and excellent ferroelectric properties of remnant polarization 32 μC/cm2, coercive force of 80 kV/cm and dielectric constant 800. Cycling fatigue characteristics and leakage current are also discussed.
