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 …

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 superconductivity at above 30 K in a FeSe-layer compound K 0.8 Fe 2 Se 2
(nominal composition) achieved by metal K intercalating in between FeSe layers. It is …

The iron pnictide and chalcogenide compounds are a subject of intensive investigations
owing to their surprisingly high temperature superconductivity. They all share the same …

The recently discovered iron arsenide superconductors appear to display a universal set of
characteristic features, including proximity to a magnetically ordered state and robustness of …

In this Letter we show that superconducting Fe 1.01 Se undergoes a structural transition at
90 K from a tetragonal to an orthorhombic phase but that nonsuperconducting Fe 1.03 Se …

In this review, the authors present a summary of experimental reports on newly discovered
iron-based superconductors as they were known at the end of 2008. At the same time, this …

α-FeSe with the PbO structure is a key member of the family of high-T c iron pnictide and
chalcogenide superconductors, as while it possesses the basic layered structural motif of …

The possibility of superconductivity in tetragonal FeS has attracted considerable interest
because of its similarities to the FeSe superconductor. However, all efforts made to pursue …

In this review, we present a summary of experimental studies of magnetism in Fe-based
superconductors. The do** dependent phase diagram shows strong similarities to the …
