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 …

Since the discovery of high T c iron-based superconductors in early 2008, more than 15,000
papers have been published as a result of intensive research. This paper describes the …

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 term'high-temperature superconductor'used to refer only to copper-based compounds—
now, iron-based pnictides have entered the frame. The comparison of these two types of …

We show that the competition between magnetism and superconductivity can be used to
determine the pairing state in the iron arsenides. To this end we demonstrate that the …

We use magnetic long-range order as a tool to probe the Cooper-pair wave function in the
iron arsenide superconductors. We show theoretically that antiferromagnetism and …

We report on a detailed investigation of the electronic phase diagram of FeSe 1-x under
pressures up to 1.4 GPa by means of ac magnetization and muon-spin rotation. At a …

We present a detailed description of two-band quasi-two-dimensional metals with s-wave
superconducting (SC) and antiferromagnetic spin-density-wave (SDW) correlations. We …

For any practical superconductor the magnitude of the critical current density, J c, is crucially
important. It sets the upper limit for current in the conductor. Usually J c falls rapidly with …

A 75 s nuclear magnetic resonance (NMR) and susceptiblity were measured in a Ba (Fe 1−
x Co x) 2 As 2 single crystal for x= 6%. NMR spectra and relaxation rates allow to show that …
