Intrinsic charge dynamics of High-Tc AFeAs(O,F) superconductors

Among the high-temperature  iron-based superconductors, AFeAs(O,F) (A – rare earth element) or 1111-type materials hold the record for the highest superconducting transition temperature observed in the bulk, up to 55K. We employed an array of state-of-the-art...
