在非常规超导体的名人堂中，硒化铁是一个摇滚明星。但美国、中国和欧洲物理学家进行的新实验发现，这种材料的磁性特性出人意料地平淡无奇。

Pengcheng Dai说：“关键结论是，与硒化铁的超导性有关的磁相关性是高度各向异性的，就像其他铁超导体一样（The key conclusion is that the magnetic correlations that are associated with superconductivity in iron selenide are highly anisotropic, just as they are in other iron superconductors）。”
