Abstract

Iron-arsenic superconductors: order restored Electron density waves have been observed in many families of superconductors, and are often considered a prerequisite for superconductivity. Recent work on iron-arsenic (or iron pnictide) compounds revealed no apparent link between density waves and superconductivity. But that link may be back on the agenda: Zabolotnyy et al. report that there is order, of a kind, in the electronic structure of Ba1−x KxFe2As2. The electronic order coexists with superconductivity and persists up to room temperature.
