PURPOSE:To prevent the infiltration of a solution through a porous surface by feeding the superconductor powder to an extremely high-temperature plasma generator and spraying the plasma from there through a nozzle to deposit on the substrate surface when forming a superconductor thin film on the substrate surface made of ferrite. CONSTITUTION:Stains such as oil, fingerprints, dust stuck to the surface of a ferrite substrate 1 are degreased with a highly volatile solvent such as Freon, thinner, rubber volatilizing material, acetone. An extremely high-temperature plasma device is arranged at a position apart from the substrate 1, the La-Sr-Cu or Y-Ba-CuO or organic superconductor powder is fed here and sprayed through a nozzle, and a superconductive thin film 2 is formed on the surface of the substrate 1 as a finished product 3. The homogeneous superconductive thin film is thereby obtained, the magnetic shielding effect is large, and it is suitable for a component for the microwave communication equipment. |
