Latest Patents
Mattheiss holds a patent for "Bismuth oxide superconductors, and devices and systems comprising such a." This patent introduces a new class of Bi-based superconductive oxides that possess a perovskite-like crystal structure. Unlike previously known Bi-based superconductors, these novel materials exhibit unmixed B-site occupancy, with all substituents occupying A-sites. This unique configuration results in marginal stability and enhanced transition temperatures compared to prior art Bi-based oxide superconductors. The materials have a composition of ABiO.sub.3-.delta., where A is Ba and at least one monovalent element, typically chosen from Na, K, Rb, and Cs. The transition temperature T.sub.c.sup.onset is approximately 13K. These superconductive materials are produced from precursor material containing an excess of the monovalent element(s), compared to the final composition. Their potential uses encompass all applications for which prior art superconductors have been proposed or utilized.
