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 …

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 …

In this Letter we show that superconducting Fe 1.01 Se undergoes a structural transition at
90 K from a tetragonal to an orthorhombic phase but that nonsuperconducting Fe 1.03 Se …

We have studied the electronic structure of the nonmagnetic LiFeAs (T c∼ 18 K)
superconductor using angle-resolved photoemission spectroscopy. We find a notable …

The iron arsenic high-temperature superconductors, exhibit particularly rich phase
diagrams. In the AE (Fe1− x T x) 2As2 family (known as '122', with AE being Ca, Sr or Ba and …

We investigate the normal state of the “11” iron-based superconductor FeSe 0.42 Te 0.58 by
angle-resolved photoemission. Our data reveal a highly renormalized quasiparticle …

We have performed high-resolution angle-resolved photoemission spectroscopy on heavily
overdoped KFe 2 As 2 (transition temperature T c= 3 K). We observed several renormalized …

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 …

Here we present a combined study of the slightly underdoped novel pnictide superconductor
Ba 1-x K x Fe 2 As 2 by means of x-ray powder diffraction, neutron scattering, muon-spin …

The precise momentum dependence of the superconducting gap in the iron-arsenide
superconductor Ba 1− x K x Fe 2 As 2 (BKFA) with T c= 32 K was determined from angle …
