| 简介 |
The present invention provides an oxide superconductive bulk magnet able to generate a strong magnetic field without breaking while being magnetized under a strong magnetic field of 5T or greater, even if the oxide superconductive bulk magnet is large with a diameter of 50 mm or greater. The oxide superconductive bulk magnet is provided with a superconductive bulk in which an RE2BaCuO5 phase is dispersed in a REBa2Cu3O7-x phase, the oxide superconductive bulk magnet being provided with a structure having a center core provided with a reinforcing material in the outer circumference portion thereof, one or more ring-shaped oxide superconductive bulk magnets provided with a reinforcing material in the outer circumference portion thereof being arranged in a nested fashion about the center core portion. RE : rare earth elements or a combination thereof; x : oxygen deficiency amount; 0 < x ≤ 0.2 |
