Title:

METHOD OF PRODUCING BIAXIALLY TEXTURED BUFFER LAYERS AND RELATED ARTICLES, DEVICES AND SYSTEMS

Document Type and Number:

WIPO Patent Application WO2005022590

Kind Code:

A3

Abstract:

A superconductor article (10) includes a substrate (12) and a first buffer film (14) disposed on the substrate (12). The first buffer film (14) has a uniaxial crystal texture characterized (i) texture in a first crystallographic direction that extends out-of-plane of the first buffer film (14) with no significant texture in a second direction that extends in-plane of the first buffer film (14), or (ii) texture in a first crystallographic direction that extends in-plane of the first buffer film (14) with no significant texture in a second direction that extends out-of-plane of the first buffer film (14). A second buffer film (16) is disposed on the first buffer film, the second buffer film having a biaxial crystal texture. A superconductor layer (18) can be disposed on the second buffer film (16). Ion-beam assisted deposition (IBAD) can be used to deposit the second buffer film (16).
