论文摘要
Hosono组发现的基于铁的分层化合物的高温超导性（Kamihara等，2006 J.Am。Chem。Soc。12810012）是令人着迷的身体现象，它仍然有许多未解决的问题。这些问题之一是基于铁的超导体（IBS）中的超导差距对称性，其中最商定的概念是多波段$ s $ - 波 - 波。最近，已经提出了单频$ p $ - 波$波的对称性的替代概念。为了反驳/重申后一个概念，在本文中，我们分析了FESE，FESE1-XTEX，BA（FE1-X（CO，NI）X）2AS2和CA10（PT4AS8）（（FE，PT）2AS2）5的FESE，FESE1-XTEX，BA（FE1-X（CO，NI）2AS2）5的平面内相干长度（（FE，pt）2AS2）5，以提取空隙 - 至关重要的调查调节率， 2 $δ$（0）/$ k $$ _ b $$ t $$ _ c $，以及在这些化合物中的特定热量比率，$δ$ c/c。结果，我们报告说，推导的比率与这些材料中的单波段$ p $ - 波超导性的概念达成了很好的一致性。
High-temperature superconductivity in iron-based layered compounds discovered by Hosono group (Kamihara et al 2006 J. Am. Chem. Soc. 128 10012) is fascinating physical phenomenon which still has many unanswered questions. One of these questions is the superconducting gap symmetry in iron-based superconductors (IBS), for which the most agreed concept is multiple-band $s$-wave symmetry. Recently, an alternative concept of single-band $p$-wave symmetry has been proposed. To disprove/reaffirm the latter concept, in this paper we analyse temperature dependent in-plane coherence length in FeSe, FeSe1-xTex, Ba(Fe1-x(Co,Ni)x)2As2 and Ca10(Pt4As8)((Fe,Pt)2As2)5 in order to extract the gap-to-critical-temperature ratio, 2$Δ$(0)/$k$$_B$$T$$_c$, and the specific-heat-jump ratio, $Δ$C/C,in these compounds. In the result, we report that deduced ratios are in a good agreement with the concept of single-band $p$-wave superconductivity in these materials.
