The iron- and nickel-based layered compounds LaOFeP (refs 1, 2) and LaONiP (ref. 3) have recently been reported to exhibit low-temperature superconducting phases with transition temperatures Tc of 3 and 5 K, respectively. Furthermore, a large increase in the midpoint Tc of up to ∼26 K has been realized in the isocrystalline compound LaOFeAs on doping of fluoride ions at the O2- sites (LaO1-xFxFeAs). Experimental observations and theoretical studies suggest that these transitions are related to… Expand

TLDR
The observation of superconductivity with zero-resistance transition temperature at 8 K in the PbO-type α-FeSe compound is reported, indicating that this compound has the same, perhaps simpler, planar crystal sublattice as the layered oxypnictides. Expand

High-pressure studies on Tc and crystal structure of iron chalcogenide superconductors
TLDR
In the case of Fe(Se1−xTex), the maximum Tc under high pressure did not exceed the Tc of FeSe, which can be attributed to the structural transition to the monoclinic phase, which may be due to the disorder induced by substituting S for Se, similar to the pressure effect on Tc for the 1111-type superconductor Ca(Fe 1−xCox)AsF.

TLDR
The present findings strongly suggest that the main reason for realization of the Tc >50 K observed in RE-1111 compounds (RE: Pr, Sm, and Gd) at ambient pressure is the merging of SC1 and SC2. Expand

From 1/T1T of 31P and 139La NMR studies of (La0.87Ca0.13)FePO, a quasi-two- dimensional electronic structure is suggested, in which the FeP layer is more conductive than the LaO layer, suggesting that novel low-energy spin dynamics develop in the SC state. Expand
