Abstract
A superconductor article includes a substrate and a first buffer film disposed on the substrate. The first buffer film includes a polycrystalline material. An IBAD (ion-beam assisted deposition) second buffer film is disposed on the first buffer film, the second buffer film having a biaxial crystal texture. A superconductor layer can be disposed on the second buffer film.
Claims9
A superconductor article, comprising:
- a substrate;
- a first buffer film disposed on said subsfrate, said first buffer film comprising a polycrystalline oxide thin film material;
- a second buffer film directly disposed on and contacting said first buffer film, said second buffer film comprising a material from the group consisting of IBAD MgO, IBAD CeO2, or IBAD RE2O3, where RE is a rare earth element, and having a biaxial crystal texture;
- and
- a superconductor layer disposed on said second buffer film.
