The magnetism of iron and nickel (invited)

Abstract

A type of theory which unifies the itinerant and localized models for metallic ferromagnets is discussed. The results of some calculations for iron and nickel are described. In particular it is found that this model can give both the correct ground state moment and Curie temperatures of the right order of magnitude (Tc = 1840°K for iron and 1200°K for nickel).
