| 摘要 |
The present invention provides an oxide superconducting bulk magnet that can have a larger superconducting bulk body without breakage when generating a high magnetic field. The outer periphery and the inner periphery of a ring-shaped oxide superconducting bulk magnet, in which a non-superconducting phase is minutely dispersed in a superconducting phase, are reinforced by ring-shaped reinforcing members. An integrated oxide superconducting bulk magnet is obtained by further combining, in a nested state on the inner side of said ring-shaped oxide superconducting bulk magnet, a ring-shaped oxide superconducting bulk magnet that has been reinforced by a reinforcing member at the outer periphery thereof, thus resulting in an integrated oxide superconducting bulk magnet that is less susceptible to breakage while generating a higher magnetic field. |
