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 …

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

Starting from a microscopic itinerant model, we derive and analyze the effective low-energy
model for collective magnetic excitations in the iron pnictides. We show that the stripe …

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 …

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 …

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

We demonstrate that the changes in the elastic properties of the FeAs systems, as seen in
our resonant ultrasound spectroscopy data, can be naturally understood in terms of …

We review the main ingredients for an unconventional pairing state in the ferropnictides, with
particular emphasis on interband pairing due to magnetic fluctuations. Summarizing the key …

Recent investigations of the superconducting iron-arsenide families have highlighted the
role of pressure, be it chemical or mechanical, in fostering superconductivity. Here we report …

A series of 122 phase BaFe 2− x Ni x As 2 (x= 0, 0.055, 0.096, 0.18 and 0.23) single crystals
was grown by the self-flux method and a dome-like Ni doping dependence of the …
