Epitaxial YBa{sub 2}Cu{sub 3}O{sub 7} on biaxially textured (001) Ni: An approach to high critical current density superconducting tapes
- and others
In-plane aligned, c-axis oriented YBa{sub 2}Cu{sub 3}O{sub 7} (YBCO) films with superconducting critical current densities, J{sub c}, as high as 700,000 amperes per square centimeter at 77 kelvin have been grown on thermo-mechanically, rolled-textured (001) Ni tapes using pulsed-laser deposition. Epitaxial growth of oxide buffer layers directly on biaxially textured Ni, formed by recrystallization of cold-rolled pure Ni, enables the growth of 1.5 micrometer-thick YBCO films with superconducting properties that are comparable to those observed for epitaxial films on single crystal oxide substrates. This result represents a viable approach for producing long-length superconducting tapes for high current, high field applications at 77 kelvin.
