Title:
OXIDE SUPERCONDUCTING BULK MAGNET MEMBER
Document Type and Number:
WIPO Patent Application WO/2011/071071
Kind Code:
A1
Abstract:
Disclosed is an oxide superconducting bulk magnet member provided with a plurality of bulk sections that have outer circumferences with mutually different dimensions and are disposed in a manner such that, from among the outer circumferences, the outer circumferences in which the aforementioned dimensions are relatively larger surround the smaller outer circumferences, and intervening sections that are disposed between mutually adjacent pairs of the aforementioned bulk sections. A space is formed between the aforementioned mutually adjacent bulk sections, the aforementioned bulk sections are oxide bulk bodies in which an RE2BaCuO5 phase has been dispersed within an REBa2Cu3O7-x phase, the bulk section in which the aforementioned outer circumference dimensions are the smallest from among the aforementioned bulk sections is a columnar shape or a ring shape, and the bulk sections outside the bulk section in which the aforementioned outer circumference dimensions are the smallest are ring shaped.
