Bilayer Conductive-Oxide Buffer Layer Structures for High-J{sub c} YBa{sub 2}Cu{sub 3}O{sub 7-d} Coated Conductors

PDF Version Also Available for Download.

Description

Epitaxial, conductive-oxide buffer layers having bilayer configurations have been deposited on biaxially textured nickel substrates (RABiTS) by rf and dc-sputter techniques. The conductive bilayer structures comprise the layer sequences of SrRuO{sub 3}/LaNiO{sub 3}/Ni and SrRuO{sub 3}/Cu/Ni. Systematic property characterizations of the buffer layers showed excellent electrical and structural properties. High-quality epitaxial YBa{sub 2}Cu{sub 3}O{sub 7-{delta}} (YBCO) films grown by pulsed-laser deposition on these structures exhibited critical current densities (J{sub c}) as high as 1.3 x 10{sup 6} A/cm{sup 2} at 77 K in self-field.
