Abstract
The superconducting structure for magnetic shielding according to the present invention comprises at least two layers of a superconducting layer and a substrate. This superconducting structure for magnetic shielding can be formed in a plate-like shape or a cylindrical shape. When the structure is prepared in three-layers by providing an intermediate layer between the superconducting layer and the substrate, the three-layered structure has improved superconducting properties. When a protective layer is provided on the superconducting layer to protect the layer, the resulting structure has improved thermal shock resistance. The intermediate layer preferably consists of a ceramic or a noble metal and the ceramic preferably consists of a glass.
