Abstract:
1. A method for producing a connecting structure between two superconductors, comprising: providing magnesium diboride superconducting core wires, each enclosed within a normally conducting metal; forming exposed ends respectively on the superconducting core wires; mixing magnesium and boron with a substance that lowers a melting temperature of magnesium when mixed with magnesium, to produce a material mixture containing 1 to 20 wt % of the substance; bringing the exposed ends of the core wires into contact with the material mixture; and allowing the exposed ends of the core wires to react with the material mixture in situ at a reaction temperature corresponding to the lower melting temperature, to thereby form a magnesium diboride and a magnesium diboride connecting structure between the superconducting core wires.
