First-principles calculation of the Curie temperature Slater–Pauling curve

Abstract

It is well known that the magnetizations as a function of the valence electron number peratom of 3d transition metal substitutional alloys form the so-called Slater–Pauling curve.Similarly, the Curie temperatures of these alloys also show systematic behaviour againstthe valence electron number. Though this fact has long been known, no attempt has beenmade so far to explain this behaviour from first principles. In this paper we calculateTC of 3d transition metal alloys in the framework of first-principles electronic structurecalculation based on the local density approximation.
