PURPOSE:To obtain a high-temperature superconductive current lead excellent in a superconductive characteristic and having a function of coping with quench, by attaining a method of preparing an oxide superconductor which can be subjected to a pressure processing under a high pressure. CONSTITUTION:A structure is constructed by laminating short-ring-shaped oxide superconductors which can be subjected to an intermediate pressure processing by uniaxial pressing. A cut is provided in a part of each of the ring-shaped superconductors and the superconductors are laminated so that the cuts are arranged at appropriate intervals. Paste of superconductive powder is applied to one end of each of the cuts, so as to increase a joining property and a critical current density of a joining part 3. The laminate structure thus prepared is put in a state of a pseudocoil in electrification and has a function of coping with quench. |
