Kazumasa Iida

摘要:

纳米复合氧化物高温大块超导体可用作准磁体。随着材料加工技术的进步,直径为26 mm的准磁体在26 K下可以产生17.6T的大磁场。这些结果是非常有吸引力的应用,涉及悬浮的永磁体上的大块超导体。事实上,已经提出并证明了使用大块超导体的其他几个应用,例如电机和磁共振显微镜。在这一章中,我们描述了几种技术,以提高磁性能的大块超导体连同一些基础知识,如相图和固化。

英文摘要:

Nanocomposite oxide high-temperature bulk superconductors can be used as quasi-magnets. Thanks to the recent progress of material processing, quasi-magnet with 26 mm diameter can generate a large field of 17.6 T at 26 K. These results are highly attractive for applications, involving levitation of permanent magnets on the bulk superconductors. Indeed, several other applications such as motors and magnetic resonance microscope using bulk superconductors have been proposed and demonstrated. In this chapter, we describe several techniques to improve the magnetic properties for bulk superconductors together with some basics such as phase diagrams and solidifications.
