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 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 …

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 …

We have established a plot of the anion height dependence of superconducting transition
temperature T c for the typical Fe-based superconductors. The plot showed a symmetric …

Here we summarize the physical properties of the newly discovered Fe-chalcogenide
superconductors. The Fe-chalcogenide superconductors are of great interest because they …

Systematic measurements of the resistivity, heat capacity, susceptibility, and Hall coefficient
are presented for single-crystal samples of the electron-doped superconductor Ba (Fe 1− x …

We report bulk superconductivity induced by an isovalent doping of phosphorus in BaFe 2
(As 1− x P x) 2. The P-for-As substitution results in shrinkage of the lattice, especially for the …

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 …
