摘要： A high temperature superconducting composite rod, wire or tape is formed by filling the open cells of a reticulated foam structure made of silver, silver alloy, gold or gold alloy with a superconducting ceramic oxide or precursor, compacting the filled structure and forming it into a rod, wire or tape and heating it to melt and/or texture the superconducting ceramic oxide. The resulting composite has continuous ligaments of metal throughout a continuous region of superconducting ceramic oxide.

摘要： A substantially single phase superconducting composition is formed from a of 1:2:3 molar ratio of fine powders of a superconducting rare earth oxide, CuO, and BaCo.sub.3. The mixed powders and shaped articles formed from the mixed powders are calcined, sintered, and cooled in an oxygen containing atmosphere. The cooling step is done slowly to convert the sample to the orthorhombic structure and to improve the superconducting properties. The article formed is a substantially single phase superconducting composition.

摘要： A multi-layer superconducting shield for shielding superconducting electronic devices from stray magnetic fields. In one embodiment the shield of the present invention comprises alternating concentric layers of a transition metal having a high transition temperature and a metal alloy formed from copper and a non-transition metal, said transition metal and metal alloy forming an interface, and a layer of A.sub.3 B-compound structure metal at the interface of said transition metal and metal alloy. The A.sub.3 B-compound structure metal is a high transition temperature superconductor.In a second embodiment the superconducting shield comprises a thin film of a high transition temperature superconducting nitride compound deposited on a cylindrical substrate. The nitride is deposited by reactive rf sputtering.
