Band model for magnetism of transition metals in the spin-density-functional formalism

Gunnarsson, O·1976·Journal of Physics F: Metal Physics

Abstract

The Hohenberg-Kohn-Sham spin-density-functional (SDF) formalism is applied. A Stoner-like band mode is derived in the SDF formalism. The solutions of the SDF equations are assumed to have Bloch character and perturbation theory is used to show that the energy splitting between spin up and spin down states is approximately wavevector independent and proportional to an energy-dependent Stoner parameter. This result makes it possible to obtain magnetic properties from the paramagnetic density of states and the Stoner parameter alone. Results in the local-spin-density approximation for the Stoner parameters of V, Fe, Co, Ni, Pd, and Pt are presented. The relative stability of the para and ferromagnetic states is found to be correct for all the elements investigated and the total magnetization compares favourably with experiment. Values for the Curie temperature are systematically too high. Experimental estimates of the Stoner parameter are compared with the calculated values and the deviation is at most a few tenths of an eV.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
