Method for making high-critical-current-density YBa{sub 2}Cu{sub 3}O{sub 7} superconducting layers on metallic substrates

Patent Feenstra, R; Christen, D; Paranthaman, M

A method is disclosed for fabricating YBa{sub 2}Cu{sub 3}O{sub 7} superconductor layers with the capability of carrying large superconducting currents on a metallic tape (substrate) supplied with a biaxially textured oxide buffer layer. The method represents a simplification of previously established techniques and provides processing requirements compatible with scale-up to long wire (tape) lengths and high processing speeds. This simplification has been realized by employing the BaF{sub 2} method to grow a YBa{sub 2}Cu{sub 3}O{sub 7} film on a metallic substrate having a biaxially textured oxide buffer layer.
Improvements in critical current density for Bi{sub 1.8}Pb{sub 0.4}Sr{sub 2}Ca{sub 2}Cu{sub 3}O{sub X} (2223) opit tapes by increasing Ag-superconductor contact

Journal Article Prorok, B C [Argonne National Lab., IL (United States)]; [Univ. of Pittsburgh, PA (United States)]; Lelovic, M; ... - Advances in Cryogenic Engineering

Recently, current flow in Bi{sub 1.8}Pb{sub 0.4}Sr{sub 2}Ca{sub 2}Cu{sub 3}O{sub X} (2223) Ag-superconductor composite tapes has been shown to flow inhomogeneously throughout the transverse cross section. Some researchers speculate that current passed through these composite tapes flows in a thin layer of the superconductor near its interface with the Ag sheath. A length of contact between the Ag and superconductor on the transverse cross-section of the tape is defined and termed the Interface Perimeter Length (IPL). Results indicate an increase of IPL results in a proportional increase in critical current and critical current density for the same cross-sectional area.
