YBCO Superconducting Thin Film Preparation on Metallic Substrates by Laser
YBa2Cu3O7-x(YBCO) superconducting thin films with Tc(R=0) of 84 K and Jc of 2×103 A/cm2 at 77 K, on polycrystalline Ni-based alloys with buffer layers of yttria-stabilized-zirconia (YSZ), are prepared in situ by excimer laser and primarily c-axis oriented. The orientation of laser-deposited YSZ buffer layers on NiCr alloys can be improved by choosing the suitable preparing parameters. The microstructure of the 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.
