摘要：

Superconducting thin films of YBa2Cu3O(y) on a metallic substrate are prepared in situ by a pulsed laser ablation technique. The growth quality of the superconducting YBa2Cu3O(y) films has been compared on YSZ/Hastelloy substrates with or without a Pt underlayer. The zero-resistance temperature, T(co), of 90.0 K and a transport critical current density, J(c), greater than 4.0 x 10(4)A/cm2 at zero field and 77.4 K were achieved when a YSZ/Pt/Hastelloy substrate was used. The insertion of a thin Pt layer at the boundary between YSZ and Hastelloy stabilized the YSZ buffer layer, resulting in the subsequent growth of a well-crystalline YBa2Cu3O(y) film.
