Multilayer Superconducting Shield and Method of Manufacturing Same.
Abstract
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 A3B-compound structure metal at the interface of said transition metal and metal alloy. The A3B-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. (Author)
