摘要 铁基超导材料的高温超导电性发生在反铁磁不稳定的区域,因此其母体的磁结构获得了广泛而深入的研究。文章简要综述了中子散射对铁基超导体磁结构的研究结果,主要按FeAs基和FeSe基两类材料进行介绍。另外,文章还介绍了掺杂导致超导时对一些体系的反铁磁序的影响。 High-temperature superconductivity in iron-based superconductors occurs near the instability of the antiferromagnetic order, so the magnetic structures in the parent compounds have been widely and deeply studied. This paper gives a brief review of the effects of neutron scat-tering on the magnetic structure in iron-based superconductors, in particular the FeAs-based and FeSe-based materials. In addition, the effects of doping on the antiferromagnetic order in some su-perconducting systems is also described.
