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 …

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

The parent phases of the Fe-arsenide superconductors harbor an antiferromagnetic ground
state. Significantly, the Néel transition is either preceded or accompanied by a structural …

We report the results of a systematic investigation of the phase diagram of the iron-based
superconductor Ba 1− x K x Fe 2 As 2 from x= 0 to x= 1.0 using high-resolution neutron and …

In a superconductor electrons form pairs and electric transport becomes dissipation-less at
low temperatures. Recently discovered iron-based superconductors have the highest …

We performed an angle-resolved photoemission spectroscopy study of BaFe 2 As 2, which
is the parent compound of the so-called 122 phase of the iron-pnictide high-temperature …

We present a combined high-resolution x-ray diffraction and x-ray resonant magnetic
scattering study of as-grown BaFe 2 As 2. The structural and magnetic transitions must be …

The negative Hall constant RH measured all over the phase diagram of Ba (Fe 1-x Co x) 2
As 2 allows us to show that electron carriers always dominate the transport properties. The …

The magnetic excitations of the iron pnictides are explained within a degenerate double-
exchange model. The local-moment spins are coupled by superexchanges J 1 and J 2 …
