Title:
SUPERCONDUCTOR ARTICLE WITH AMORPHOUS BUFFER LAYER COMPRISING TANTALUM
Document Type and Number:
WIPO Patent Application WO2003044873
Kind Code:
A3
Abstract:
Described is an article having a substrate (12); a thermochemically stable, amorphous layer (14) comprising tantalum or a tantalum-containing material; a layer of material having a rock salt-like structure (16) having substantial alignment both in-plane and out-of-plane; a superconducting layer (20) formed on said rock salt-like layer having substantial in-plane and out-of-plane alignment; wherein said rock salt-like layer provides a template for the epitaxial growth of said superconducting layer; an optional buffer layer (18) or layers having substantial alignment both in-plane and out-of-plane, between the rock salt-like structure layer and the superconducting layer; and an optional protective layer (22) covering the superconducting layer.
