Title:
OXIDE SUPERCONDUCTING BULK MAGNET
Document Type and Number:
WIPO Patent Application WO/2014/189043
Kind Code:
A1
Abstract:
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.
