Competing orders and role of fluctuations in FeSe
Above a critical pressure associated with the onset of magnetic order, superconducting and magnetic fluctuations exist over a wide temperature range above their respective bulk transition temperatures. Superconductivity in FeSe under pressure is bulk and competes with magnetism; measurements reveal fluctuations of superconductivity and magnetism likely due to their competing nature similar to other high-Tc superconductors.
