摘要： PURPOSE:To enable a superconducting coil made of a filmed superconducting material to be manufactured easily by laminating a heat conductive film, a superconducting film and an insulating film on the surface of a substrate in a spiral form. CONSTITUTION:The pressure inside a vacuum container 4 is reduced, and while a substrate 5 is rotated in one direction, working gas such as argon, helium, etc., is supplied to the rear end part of first - third spray nozzles 6, 9, 12. Grains of Cu, grains of composite oxide superconducting materials containing CuxOy radical grains of insulating material such as Al2O3, Zr, YSZ are supplied to the inside of the tip part of spray nozzles 6, 9, 12 respectively. And by operating first - third electrodes 8, 11, 14, plasma jets are generated from a first spray nozzle 6 to a first electrode 7, from a second spray nozzle 9 to a second electrode 10, and from a third spray nozzle 12 to a third electrode 13 respectively. In this way, on the surface of the substrate 5, a heat conductive film 15, a superconducting film 16, and an insulating film 17 are laminated in a spiral form. This makes it possible to manufacture a superconducting coil easily.

摘要： PURPOSE:To form a film having high superconducting characteristic on a substrate by radiating O-ions toward the surface of the substrate in a stag for depositing a compound oxide to the surface of the substrate by a laser vapor deposition process and compensating deficient amt. of oxygen in the film. CONSTITUTION:A substrate 3 (material to be subjected to vapor deposition) and a sintered body 2 of a compound oxide (vapor deposition source) contg. CuxOy group are disposed in an evacuated chamber 1. The sintered body 2 is evaporated by the irradiation with laser beam, and evaporated material is deposited to the substrate 3. In this stage, the inside of the evacuated chamber 1 is held in O2 atmosphere, and oxygen ions are radiated from an ion gun 11 toward the surface of the substrate 3.

摘要： PURPOSE:To efficiently feed oxygen insufficient in film components and obtain a superconducting material having a film having excellent superconducting characteristics on the surface of a substrate, by carrying out high-frequency discharge between a superconducting material having a film of a specific superconducting substance formed on the surface of the substrate and an electrode placed parallel thereto in an O2-containing atmosphere. CONSTITUTION:For example, the interior of a vacuum vessel 4 is decompressed to a prescribed vacuum degree and laser beams (a) are directed to irradiate a vapor deposition source 5 consisting of a calcined compound oxide body containing CuxOy group. The evaporated particles are then deposited on the surface of a substrate 2 heated with a heater 6 to afford a superconducting material 1 having a film 3 of a compound oxide superconducting substance containing the CuxOy groups on the substrate 2. The resultant material 1 is subsequently placed in a vessel 10 of an O2-containing atmosphere and an electrode 11 is arranged in parallel to the film 3 with a prescribed interval therefrom. The interior of the vessel 10 is then kept at, e.g., about 200Torr pressure, to actuate a high-frequency power source 13 and carry out high-frequency discharge between the superconducting material 1 and the electrode 11 and excite and permeate O2 within the resultant high-frequency discharge zone into the film 3. Thereby oxygen insufficient in the film 3 components is supplied to impart excellent superconducting characteristics to the film 3.
