Abstract: The present invention relates to a superconductor and a method of manufacturing the same. The superconductor comprises: a substrate having a tape shape that extends in a first direction and having surfaces which are defined as a top surface, a bottom surface, and both side surfaces; a superconductive layer positioned on the top surface of the substrate; a first stabilizing layer disposed on the superconductive layer and containing a first metal; a protective layer disposed on the first stabilizing layer and containing a second metal which is different from the first metal; and an first alloy layer disposed between the stabilizing layer and the protective layer and containing the first and second metals.

Abstract: A super conductor is formed by a process including a first step of forming liquid-phase rare earth-copper-barium oxide by heat treating a superconductor precursor including a rare earth element, barium, and copper, a second step of forming a first superconductor of the rare earth-copper-barium oxide that is epitaxially grown from the liquid-phase rare earth-copper-barium oxide, and a third step of forming a second superconductor of the rare earth-copper-barium oxide by heat treating the first superconductor, wherein the heat treatment of the third step is performed in an atmosphere in which the rare earth-copper-barium oxide has no liquid phase.

Abstract: Provided is a method of forming a superconducting wire. In the method, a buffer layer is formed on a substrate. Then, a superconducting precursor film is formed on the substrate formed with the pinning seed layer. Thereafter, the substrate formed with the superconducting precursor film is heat-treated to form a superconducting film including magnetic flux pinning centers on the substrate. The magnetic flux pinning centers comprise at least one element included in the pinning seed layer, and at least one element included in the superconducting precursor film.
