The structures, the phase diagrams, and the appearance of a neutron resonance signaling
an unconventional superconducting state provide phenomenological evidence relating the …

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 recently discovered Fe-pnictide and chalcogenide superconductors display low-
temperature properties suggesting superconducting gap structures which appear to vary …

In iron pnictides, we find that the moderate electron-phonon interaction due to the Fe-ion
oscillation can induce the critical d-orbital fluctuations, without being prohibited by the …

I review theoretical ideas and implications of experiments for the gap structure and symmetry
of the Fe-based superconductors. Unlike any other class of unconventional …

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 …

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 …

We study the mechanism of orbital or spin fluctuations due to multiorbital Coulomb
interaction in<? format?> iron-based superconductors, going beyond the random-phase …

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