Abstract
YBa2Cu3O7-y bulk as a high temperature oxide superconducting conductor has the high critical temperature of 92 K. YBa2Cu3O7-y bulk superconductors have been fabricated by a seeded melting growth. Magnetic properties were studied by using superconductor of melted YBa2Cu3O7-y oxides. It was demonstrated that Y2BaCuO5 particles acts as a pinning center which plays an important role on the magnetic properties. The thickness of the upper and lower pellets of the YBa2Cu3O7-y bulk was formed at 40 mm with 55 g of the composition, and the YBa2Cu3O7-y superconductor was manufactured through a heat treatment process. Manufacturing the superconducting bulk, it is possible to improve the pore density of the superconducting bulk by providing a path through which oxygen could be emitted.
