High-temperature superconductivity in the iron-based materials emerges from, or sometimes
coexists with, their metallic or insulating parent compound states. This is surprising, as these …

High-transition temperature (high-T c) superconductivity in the iron pnictides or
chalcogenides emerges from the suppression of the static antiferromagnetic order in their …

We report the results of a systematic investigation of the phase diagram of the iron-based
superconductor Ba 1− x K x Fe 2 As 2 from x= 0 to x= 1.0 using high-resolution neutron and …

In a superconductor electrons form pairs and electric transport becomes dissipation-less at
low temperatures. Recently discovered iron-based superconductors have the highest …

A theory of superconductivity in the iron-based materials requires an understanding of the
phase diagram of the normal state. In these compounds, superconductivity emerges when …

High-temperature superconductivity in iron pnictides occurs when electrons and holes are
doped into their antiferromagnetic parent compounds. Since spin excitations may be …

Although the pairing mechanism of Fe-based superconductors (FeSCs) has not yet been
settled with consensus with regard to the pairing symmetry and the superconducting (SC) …

The present article reviews recent experimental investigations of spin dynamics in iron-
based superconductors and their parent compounds by means of inelastic neutron …

We reconsider the effect of disorder on the properties of a superconductor characterized by
a sign-changing order parameter appropriate for Fe-based materials. Within a simple two …

The upper critical field H c 2 (T) of the multiband superconductor KFe 2 As 2 has been
studied via low-temperature thermal expansion and magnetostriction measurements. We …
