Abstract
A method of manufacturing a superconducting thin film material includes a vapor phase step of forming a superconducting layer by a vapor phase method and a liquid phase step of forming a superconducting layer by a liquid phase method so that the latter superconducting layer is in contact with the former superconducting layer. Preferably, the method further includes the step of forming an intermediate layer between the former superconducting layer and a metal substrate. The metal substrate is made of a metal, and preferably the intermediate layer is made of an oxide having a crystal structure of any of rock type, perovskite type and pyrochlore type, and the former superconducting layer and the latter superconducting layer both have an RE123 composition. Accordingly, the critical current value can be improved.
