    摘要： A method of manufacturing a superconducting thin film material includes the step of forming an intermediate layer (2), the step of forming one superconducting layer (3) to be in contact with the intermediate layer (2) and the step of forming another superconducting layer (4) by a vapor phase method to be in contact with the one superconducting layer (3). Between the step of forming the intermediate layer (2) and the step of forming the one superconducting layer (3), the intermediate layer (2) is kept in a reduced water vapor ambient or reduced carbon dioxide ambient or, between the step of forming one superconducting layer (3) and the step of forming another superconducting layer (4), the one superconducting layer (3) is kept in a reduced water vapor ambient or reduced carbon dioxide ambient. Thus, the critical current value can be improved.

    摘要： This invention provides a heat treatment apparatus for an oxide superconducting wire that is easy to control atmosphere during baking and can realize a high manufacturing speed. A heat treatment apparatus (1) comprises a heat treating furnace (4) and a cylindrical rotator (5), rotatable about a horizontal rotating axis, provided within the heat treating furnace (4). The rotator (5) in its cylindrical body (5a) have a number of through-holes (5b) formed evenly over the whole surface of the cylindrical body (5a). One end of the cylindrical body (5a) is hermetically sealed by a lid. On the other end, a gas discharge pipe (7) for discharging gas within the cylindrical body to the outside of the heat treating furnace (4) is connected to the lid. A plurality of gas supply pipes (8) are symmetrically provided separately from each other on the outer surface of the cylindrical body (5a). A number of gas jet holes are formed in each of the gas supply pipe (8) so as to jet atmosphere gas toward the surface of the cylindrical body. A tape-shaped wire (6) formed of a precursor film of a YBCO superconducting layer is wound around the rotator (5) for heat treatment for superconductor formation.
