摘要：

Epitaxial YBa2CU3O7-delta (YBCO) thin films were deposited on (100) MgO using platinum and SrRuO3 (SRO) buffer layers by pulsed laser deposition. The films were (001) textured normal to substrate surface with a high degree of in-plane orientation with respect to the substrate's major axes. YBCO films showed superconducting transition temperature (T-co) at 91 K and critical current densities were found to be 2-3 X 10(6) A/cm(2) at 77 K and zero field. An ion beam minimum channeling yield of 16% was obtained for YBCO films, indicating high crystallinity. The orientation relationship for this epitaxial multilayer structure was found to be (100) YBC parallel to(100) SR parallel to(100)Pt parallel to(100) MgO. This result showed that high-quality superconducting thin films can be deposited on metal with an appropriate buffer layer.
