摘要： A magnetic field shield which is characterized in that it includes at least one composite lamination including a thin film of the superconductor and a metal layer laminated with the thin film of the superconductor having a thickness not more than that obtained at the turning point where the magnetic field shielding effect of a single film of the superconductor changes from an abrupt increase to a gradual increase and the film thickness is less than 2 .mu.m.

摘要： A large-area superconductor magnetic shield comprising a plurality of small superconductor unit layers stuck onto the surface of a large-area substrate, wherein the external peripheral sections of the adjacent unit layers are overlapped mutually or the end sections of the adjacent unit layers are abutted mutually such that the adjacent unit layers do not make contact with one another. Compared with conventional magnetic shields, the magnetic shielding amount at the overlapping sections of the magnetic shield of the present invention is substantially greater.

摘要： A static magnetic refrigerator comprising a magnet generating a high-intensity magnetic field, a magnetic working material disposed in the high-intensity magnetic field, a magnetic shield disposed between the magnet and the magnetic working material, and a rotating means for rotating the magnetic shield, the magnetic shield comprising a pair of nearly parallel flat plates or a pair of outwardly curved plates facing each other and made of a superconductor, and the magnetic working material is accommodated in the inner space form by the pair of the flat or curved plates, whereby a magnetization process wherein the magnetic working material is magnetized in the high-intensity magnetic field by way of rotating the magnetic shield at a position allowing the permeation of the magnetic field through the magnetic working material via the pair of the flat or curved plates and a demagnetization process wherein the magnetic working material is demagnetized by way of further rotating the superconducting magnetic shield at another position permitting the shield of the magnetic field via the pair of the flat or curved plates are repeated by the rotating means so that the magnetic working material generates coldness.

摘要： A superconductor for magnetic field shielding which is characterized in that it includes at least one composite lamination including a thin film of the superconductor and a metal layer laminated with the thin film of the superconductor having a thickness not more than that obtained at the turning point where the magnetic field shielding effect of a single film of the superconductor changes from an abrupt increase to a gradual increase as the thickness of the superconductor film increases. This superconductor for magnetic field shielding has an extremely great magnetic field shielding effect even though the superconductor is in thin layers.
