PURPOSE:To obtain a superconductive wire with the optional shape and diameter by holding a raw material while heating it in the atmosphere of the oxygen- containing gas and the organic compound and/or halogenide of elements other than oxygen among the elements constituting a superconductor and generating an oxide superconductor thin film on the surface by the oxidation reaction. CONSTITUTION:A copper wire with an optional diameter is inserted into a reaction tube or the like and allowed to pass through the mixed gas atmosphere of the vapor mixed gas of Y (CH3C5H4)3, Ba(C5H5)2, Cu (acac)2 with the mixing ratio of 1:1:1 and the oxygen gas with the oxygen partial pressure of 100Torr while being externally heated at 850 deg.C to generate an oxide superconductor film with the thickness of about 10mum. The investigation of this result indicates that the electric resistance starts to be decreased around 90K and becomes zero at about 80K. Other materials than copper may be used as the raw material, and this is applicable to In, optical fiber or the like. |
