Kamihara and coworkers' report of superconductivity at T c= 26 K in fluorine-doped
LaFeAsO inspired a worldwide effort to understand the nature of the superconductivity in this …

The surprising discovery of superconductivity in layered iron-based materials, with transition
temperatures climbing as high as 55 K, has led to thousands of publications on this subject …

The recently discovered Fe-pnictide and chalcogenide superconductors display low-
temperature properties suggesting superconducting gap structures which appear to vary …

The response of the worldwide scientific community to the discovery in 2008 of
superconductivity at T c= 26 K in the Fe-based compound LaFeAsO1− x F x has been very …

We show that electron-and hole-doped BaFe 2 As 2 are strongly influenced by a Mott
insulator that would be realized for half-filled conduction bands. Experiments show that …

The superconductor Sr 4 V 2 O 6 Fe 2 As 2 with transition temperature at 37.2 K was
successfully fabricated. It has a layered structure with the space group of p 4/nmm and with …

Since the first report on superconductivity at 26 K in F-doped LaOFeAs at the end of
February 2008, the iron pnictide superconductor family has been quickly expanded to six …

The theoretical need to study the properties of the Fe-based high-T c superconductors using
reliable many-body techniques has highlighted the importance of determining what is the …

We report the synthesis, crystal structure, and physical properties of a quinary iron arsenide
fluoride, KCa2Fe4As4F2. The new compound crystallizes in a body-centered tetragonal …

The specific heat of high-purity Ba 0.68 K 0.32 Fe 2 As 2 single crystals with the highest
reported superconducting T c= 38.5 K was studied. The electronic specific heat C p below T …
