Fabrication of high Jc oxide superconductors by a melt process and their critical current characteristics

研究成果: Article

抄録

YBa2Cu3Ox powders were rapidly heated to the Y2O3 plus liquid region and quenched using copper hammers. The quenched plates were again heated to the Y2BaCuO5 plus liquid region and slowly cooled in a thermal gradient. The process enabled unidirectional growth of the superconducting phase. Magnetization measurements revealed that magnetic properties of the melt processed samples could be understood in terms of a Bean critical state model. The samples attained Jc values exceeding 104 A/cm2 at 77K and 1T. Flux creep was not observed.
