Abstract C-axis oriented Y1Ba2Cu3O7-x(YBCO) thin films and PbZr0.52Ti0.48O3(PZT)/(YBCO) heterostructures were deposited on single-crystal LaAIO3 by Nd:YAG pulsed laser deposition. The results showed that the YBCO films exhibited superconducting transition temperature above 86 K and ion beam channeling minimum yields xmin of 49%, indicating the relatively good quality of YBCO films deposited on the LaAIO3 substrate. The PZT films in situ grown on the YBCO films were epitaxially c-axis oriented with a saturation polarization and remanence as high as 57μC/cm2 and 39μC/cm2 (at 204 kV/cm), respectively. The coercive field of PZT films is about 55 kV/cm.
