  • Superconducting film on a flexible two-layer zirconia substrate
    Patent number: 5145832
    Abstract: A flexible superconducting wire element comprising a flexible tape of partially stabilized (.about.3 mole % yttria) yttria-stabilized zirconia (YSZ), a buffer layer of fully stabilized (between 8 and 18 mole % yttria, preferably 9 mole %) YSZ deposited on the flexible tape, and a high-temperature, perovskite superconductor such as YBaCuO deposited on the buffer layer. The tape provides the strength while remaining flexible. The buffer layer is flexible because of its thinness (.about.100 nm), but provides a good crystallographic template for the growth of oriented perovskite superconductors. Thereby, the superconducting properties of the wire element approach those of a superconducting film deposited on a rigid substrate.
