中文摘要：

最新发现的基于铁的高温度超导体表明了富有的物理性质。这里，我们在一些在上面的关键字段和它的 anisotropy 的最近的研究上给简短评论基于铁的超导体(FeSCs ) 的典型系列。尽管有他们分层的水晶结构的人物，所有 FeSCs 拥有极其大的上面的关键字段和超导性的弱 anisotropy，在分层的超导体之中是唯一的。这些特别性质以后显示 FeSCs 的潜在的应用。基于 FeSCs 的试验性的事实，我们将讨论对在超导的配对机制的理论分析上在高磁场和它的限制碎的可能的机制。

英文摘要：

The newly discovered iron-based high temperature superconductors have demonstrated rich phys- ical properties. Here we give a brief review on the recent studies of the upper critical field and its anisotropy in a few typical series of the iron-based superconductors （FeSCs）. In spite of their characters of a layered crystal structure, all the FeSCs possess an extremely large upper critical field and a weak anisotropy of superconductivity, being unique among the layered superconductors. These particular properties indicate potential applications of the FeSCs in the future. Based on the experimental facts of the FeSCs, we will discuss the possible mechanisms of pair breaking in high magnetic fields and its restrictions on the theoretical analysis of the superconducting pairing mechanisms.
