SUPERCONDUCTING BEARING AND MAGNETICALLY LEVITATING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a superconducting member having little loss at rotation and translation, and to provide a magnetic levitation device. SOLUTION: This is a superconducting member where superconducting layers being made by jointing a plurality of superconductors are stacked. This is a superconducting member which is excellent in captured magnetic field properties, with (a1) the critical current density of the superconductors being different between layers and (b1) the junction plane of one superconductor being positioned in between the junction planes of other superconductors in the other layers. This is a superconductor member which is superior in captured magnetic field property, being characterized by (a2) all or some of the superconductors in one layer being made into a crest form and (b2) the junction planes of the superconductors in other layers being positioned at the apex of the above the crest-form part.
