Title:
NUCLEAR MAGNETIC RESONANCE MAGNET UNIT, AND NUCLEAR MAGNETIC RESONANCE MAGNETIC FIELD GENERATING DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/067458
Kind Code:
A1
Abstract:
This nuclear magnetic resonance magnet unit is provided with a plurality of oxide superconducting bulk bodies which are ring-shaped and have a structure in which an RE2BaCuO5 phase is dispersed in a single-crystal REBa2Cu3Oy phase, wherein: the plurality of oxide superconducting bulk bodies are each stacked coaxially and in a coaxial direction to form a stacked body; the plurality of oxide superconducting bulk bodies include a first oxide superconducting bulk body disposed at one end or both ends of the stacked body, and a second oxide superconducting bulk body adjacent to the first oxide superconducting bulk body; and the outer diameter, the radial direction thickness, or the volume of the first oxide superconducting bulk body is smaller than the outer diameter, the radial direction thickness, or the volume of the second oxide superconducting bulk body.
