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 …

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 have performed an angle-resolved photoemission spectroscopy study of the new iron-
based superconductor K 0.8 Fe 1.7 Se 2 (T c∼ 30 K). Clear band dispersion is observed …

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 …

We show that the competition between magnetism and superconductivity can be used to
determine the pairing state in the iron arsenides. To this end we demonstrate that the …

We report the first NMR investigation of spin dynamics in the overdoped
nonsuperconducting regime of Ba (Fe 1-x Co x) 2 As 2 up to x= 0.26. We demonstrate that …

The in-plane resistivity ρ and thermal conductivity κ of the FeAs-based superconductor KFe
2 As 2 single crystal were measured down to 50 mK. We observe non-Fermi-liquid behavior …

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 …

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 use high-resolution angle-resolved photoemission to study the electronic structure of the
BaFe 2 As 2 pnictides. We observe two electron bands and two hole bands near the X …
