摘要
Band structures of ErAs and ErxSc1-xAs alloys (treated in virtual crystal approximation) calculated by the linear muffin-tin orbital method including spin-orbit coupling as well as spin polarization are presented. Corrections to the local spin density approximation are included by a constant upwards shift of the Er-5d derived conduction bands adjusted to yield the observed carrier concentration. Fermi-surface and effective mass parameters are presented and used to simulate the Shubnikov-de Haas spectrum which is shown to be in goad agreement with the experimental spectrum.
