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 critical current of a superconductor can be different for opposite directions of current flow
when both time-reversal and inversion symmetry are broken. Such non-reciprocal behaviour …

The normal-state charge transport is studied systematically in high-quality single crystals of
BaFe 2 (As 1− x P x) 2 (0≤ x≤ 0.71). By substituting isovalent P for As, the spin-density …

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 …

Since the first report on superconductivity at 26 K in F-doped LaOFeAs at the end of
February 2008, the iron pnictide superconductor family has been quickly expanded to six …

Measurements of London penetration depth, a sensitive tool to study multiband
superconductivity, have provided several important insights into the behavior of Fe-based …

Among various parent compounds of iron pnictide superconductors, EuFe 2 As 2 stands out
due to the presence of both spin density wave of Fe and antiferromagnetic (AFM) ordering of …

We discover a robust coexistence of superconductivity and ferromagnetism in an iron
arsenide RbEuFe 4 As 4. The new material crystallizes in an intergrowth structure of RbFe 2 …

In many pnictides the superconductivity coexists with ferromagnetism in an accessible range
of temperatures and compositions. Recent experiments revealed that when the temperature …
