Epitaxial YBa[sub 2]Cu[sub 3]O[sub 7[minus][delta]] (YBCO) thin films were deposited on (100) MgO using platinum and SrRuO[sub 3] (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 ([ital T][sub co]) at 91 K and critical current densities were found to be 2--3[times]10[sup 6] A/cm[sup 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) YBCO[parallel](100) SRO[parallel](100)Pt[parallel](100) MgO. This result showed that high-quality superconducting thin films can be deposited on metal with an appropriate buffer layer.
