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 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 …

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

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

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 …

The mechanism of high-temperature superconductivity in the newly discovered iron-based
superconductors is unresolved. We use spectroscopic imaging–scanning tunneling …

High-resolution x-ray diffraction measurements reveal an unusually strong response of the
lattice to superconductivity in Ba (Fe 1-x Co x) 2 As 2. The orthorhombic distortion of the …

We use bulk magnetic susceptibility, electronic specific heat, and neutron scattering to study
structural and magnetic phase transitions in Fe 1+ y Se x Te 1− x. Fe 1.068 Te exhibits a first …

The recently discovered FeAs-based superconductors are a new, promising set of materials
for technological and basic research. They offer transition temperatures as high as 55 K as …

Single crystalline samples of Ba (Fe 1− x Co x) 2 As 2 with x< 0.12 have been grown and
characterized via microscopic, thermodynamic, and transport measurements. With …
