Epitaxial yttria-stabilized zirconia on biaxially-textured (001) Ni for YBCO coated conductor

Epitaxial YSZ film was deposited directly on biaxially-textured (001) Mi ta pes using pulsed-laser deposition. Nucleation of the YSZ film on Wi is achi eved without the intentional removal of the native oxide from the Mi (001) surface. The epitaxial YSZ layer grown on the Wi (001) surface was used as a single buffer layer for a high temperature superconducting coated conduct or architecture, yielding YBa2Cu3O7 films with critical current density of 1 MA/cm(2) at 77 K. This architecture eliminates the necessity for a multil ayer buffer architecture, as high J(c) superconducting films are achieved w ith no intermediate buffer layer between the (001) YSZ and the biaxially te xtured metal.
