REBCO (Rare Earth Barium Copper Oxide)
中国领先。但也只能算是高温超导。
我看看美国韩国的神迹
常温超导体啥时候出来。实用化啊。
REBCO has been used to create test magnets that can handle currents of over 40,000 amperes.
REBCO is also being used to create superconducting magnets that can generate fields of over 30 tesla.
已经是目前很不错的方案了, 液氮条件.
除非美国大学那个常温超导实现, 或者韩国常温悬浮实现实用化.
