HIGH TEMPERATURE SUPERCONDUCTING THICK FILMS FIELD OF THE INVENTION

摘要

An article including a substrate (10), a layer of an inert oxide material (12) upon the surface of the substrate (10), a layer (14) of an amorphous oxide or oxynitride material upon the inert oxide material layer (12), a layer of an oriented cubic oxide material (16) having a rock-salt-like structure upon the amorphous oxide material layer (14) is provided together with additional layers such as at least one layer of a buffer material (20, 22) upon the oriented cubic oxide material layer (16) or a HTS top-layer (24) of YBCO directly upon the oriented cubic oxide material layer (16). With an HTS top-layer (24) of YBCO upon at least one layer of a buffer material (20, 22) in such an article, Jc's of 1.4 X 106 A/cm<2> have been demonstrated with projected Ic's of 210 Amperes across a sample 1 cm wide.
