Oxide superconducting bulk magnet member |
摘要 |
An oxide superconducting bulk magnet member includes a plurality of bulk sections that have outer circumferences with outer circumferential dimensions different from each other and are disposed in a manner such that among the outer circumferences, an outer circumference in which the outer circumferential dimension is relatively large surrounds a small outer circumference; and interposed sections that are disposed between a pair of the bulk sections that are adjacent to each other, wherein a gap is formed between the bulk sections adjacent to each other, each of the bulk sections is an oxide bulk in which an RE2BaCuO5 phase is dispersed within an REBa2Cu3O7-x phase, and a bulk section having the smallest outer circumferential dimension among the bulk sections has a columnar shape or a ring shape, and bulk sections other than the bulk section having the smallest outer circumferential dimension have a ring shape. |

1. An oxide superconducting bulk magnet member comprising:
a plurality of bulk sections that have outer circumferences with outer circumferential dimensions different from each other and are disposed in a manner such that among the outer circumferences, an outer circumference in which the outer circumferential dimension is relatively large surrounds a small outer circumference; and interposed sections that are disposed between a pair of the bulk sections that are adjacent to each other, wherein a gap is formed between the bulk sections adjacent to each other, each of the bulk sections is an oxide bulk in which an RE2BaCuO5 phase is dispersed within an REBa2Cu3O7-x phase, a bulk section having a smallest outer circumferential dimension among the bulk sections has a columnar shape or a ring shape, and bulk sections other than the bulk section having the smallest outer circumferential dimension have a ring shape, and the interposed sections are formed of a resin, grease, or solder. |
