摘要： A magnetic shield which comprises: a plurality of metallic cylinders connected to each other in the axial direction thereof, each of the plurality of cylinders having at one end thereof an engaging section for receiving an end of an adjacent metallic cylinder to be connected thereto; and a film of a composite oxide superconducting material containing a Cu.sub.x O.sub.y -radical, formed on the entire inner surface of each of the plurality of cylinders, including the inner surface of the engaging section thereof. The above-mentioned magnetic shield can easily be scaled up and has a high magnetic shielding effect.

摘要： A method for manufacturing a superconducting article, comprising the steps of: forming a first layer comprising a mixture of LnBa.sub.2 Cu.sub.3 O.sub.x and Ln.sub.2 BaC oxid, on the surface of a substrate, said Ln being an optional rare earth element; then locally and sequentially/heating and melting the first layer to locally and sequentially form a molten pool of the mixture of the first layer, and causing the molten pool of the first layer to locally and sequentially solidify, thereby arranging the a-b plane of the crystal of the mixture of the first layer in parallel with the surface of the substrate; then forming a second layer comprising a mixture of at least CuO and BaCuO.sub.2 on the surface of the first layer; and then melting the mixture of the second layer to cause the resultant melt of the mixture of the second layer to diffusion-react with Ln.sub.2 BaCu oxide, in the first layer so as to convert the first and second into a film of a superconducting substance comprising LnBa.sub.2 Cu.sub.3 O.sub.x, in which the a-b plane of the crystal thereof is arranged in parallel with the surface of the substrate; thereby manufacturing a superconducting article comprising the substrate and the film of the superconducting substance formed on the surface of the substrate.
