摘要：

C-axis oriented Y1Ba2Cu3O7-x (YBCO) thin films and PbZr0.52 Ti0.48O3 (PZT)/(YBCO) heterostructures were deposited on single-crystal LaAlO3 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 chi(min) of 49%, indicating the relatively good quality of YBCO films deposited on the LaAlO3 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 57 mu C/cm(2) and 39 mu C/cm(2) (at 204kV/cm), respectively. The coercive field of PZT films is about 55 kV/cm.
