  • Substrates for superconductors
    Patent number: 6428635
    Abstract: An alloy capable of forming a (100) [001] cube-texture by thermo-mechanical techniques has 5 to 45 atomic percent nickel with the balance being copper. The alloy is useful as a conductive substrate for superconducting composites where the substrate is coated with a superconducting oxide. A buffer layer can optionally be coated on the substrate to enhance deposition of the superconducting oxide. Methods for producing the alloys, substrates, and superconductors are included.
