Coexisting itinerant and localized electrons

摘要: The surprising discovery of high-T c superconductivity in iron-based compounds has prompted an intensive investigation on the role interaction and magnetism these materials. Based general features multi-bands intermediate coupling strengths, a phenomenological theory based coexistence itinerant electrons local moments been proposed to describe low-energy physics superconductors. It provides unified minimal framework understand magnetic, superconducting, normal phases materials, which is subject further microscopic justification experimental verification.
