Abstract
The YBa2Cu3O7-x (YBCO) superconducting thin films with Tc(R equals 0) of 84 K and Jc of 2 X 103 A/cm2 at 77 K, on polycrystalline Ni-based alloys with buffer layers of Yttria-Stabilized-Zirconia (YSZ), have been prepared in situ by excimer laser. The orientation of laser-deposited YSZ buffer layers on NiCr alloys can be improved by choosing the suitable preparing parameters. The microstructure of YBCO thin films, investigated with a scanning tunneling microscopy, shows that the spiral growth structure may be an important characteristic of the high quality YBCO superconducting thin films.
