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 …

Almost a decade has passed since the serendipitous discovery of the iron-based high
temperature superconductors (FeSCs) in 2008. The fact that, as in the copper oxide high …

The record superconducting transition temperature (T c) for the iron-based high-temperature
superconductors (Fe-HTS) has long been 56 K. Recently, in single-layer FeSe films grown …

Despite decades of intense research, the origin of high-temperature superconductivity in
cuprates and iron-based compounds is still a mystery. Magnetism and superconductivity are …

Superconductivity and ferromagnetism are two antagonistic cooperative phenomena, which
makes it difficult for them to coexist. Here we demonstrate experimentally that they do coexist …

We report an unprecedented anisotropic superconductivity in Eu (Fe 0.75 Ru 0.25) 2 As 2
single crystals. The in-plane resistivity (ρ ab) and vertical magnetization (M c) show a …

We use angle-resolved photoemission spectroscopy and density functional theory
calculations to study the electronic structure of CaFe 2 As 2 in the collapsed tetragonal (CT) …

The electronic structure of LaFeAsO, a parent compound of iron-arsenic superconductors, is
studied by angle-resolved photoemission spectroscopy. By examining its dependence on …

Employing high resolution photoemission spectroscopy, we studied the temperature
evolution of the electronic structure of EuFe 2 As 2, a unique pnictide, where …

We measured the electronic structure of an iron arsenic parent compound LaFeAsO using
angle-resolved photoemission spectroscopy (ARPES). By comparing with a full-potential …
