Superconductor and method of manufacturing the same

摘要

A method of manufacturing a superconductor is carried out by first preparing a material composed of Y1Ba2Cu3O7. This material is heated/molten in a platinum crucible. A melt thus obtained is drawn out from a high-temperature frame provided above the platinum crucible and heated to a temperature exceeding the melting point of the material. The melt thus drawn out is cooled by natural standing, to be solidified. As the result, an elongated superconductor composed of Y1Ba2Cu3O7 can be obtained. This superconductor enters a superconductive state at 90 K.
