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 …

I review recent works on the symmetry and the structure of the superconducting gap in Fe-
based superconductors (FeSCs) and on the underlying pairing mechanism in these …

We show that electron-and hole-doped BaFe 2 As 2 are strongly influenced by a Mott
insulator that would be realized for half-filled conduction bands. Experiments show that …

Angle resolved photoemission spectroscopy (ARPES) reveals the features of the electronic
structure of quasi-two-dimensional crystals which are crucial for spin and charge ordering …

Using resistivity, heat-capacity, thermal-expansion, and susceptibility measurements we
study the normal-state behavior of KFe 2 As 2. Both the Sommerfeld coefficient (γ≈ 103 mJ …

Superconductivity has recently been discovered in several families of iron-based
compounds, but despite intense research even such basic electronic properties of these …

Two-band superconductivity has become an important topic over the past ten years.
Extensive experimental and theoretical studies started with MgB 2 and are now focused on …

We investigate the temperature dependence of the lower critical field H c 1 (T) of a high-
quality FeSe single crystal under static magnetic fields H parallel to the c axis. The …
