铁磷属元素的空间非均匀性:条纹的形成

On spatial non-homogeneity in iron pnictides: formation of stripes

Lev P. Gor'kov, Gregory B. Teitel'baum

摘要:

在铁磷属化合物中发现了介观尺度上的反铁磁性和超导电性的异质共存。我们建议和讨论的情况下,在适当的掺杂或施加的压力下,由固有的SDW状态的pnictides的域壁的形成所造成的异质性。超导性将从调制的SDW结构中出现。这种现象类似于超导体中的FFLO相。

英文摘要:

The heterogeneous coexistence of antiferromagnetism (SDW) and superconductivity on a mesoscopic scale was observed in iron-pnictides in many recent experiments. We suggest and discuss the scenario in which the heterogeneity is caused by formation of domain walls inherent to the SDW state of pnictides at a proper doping or under applied pressure. Superconductivity would emerge from the modulated SDW structure. The phenomenon is akin to the FFLO-phase in superconductors.
