Photoemission and magnetic effects in NaCrS₂

Abstract

X-ray and angle-resolved ultraviolet photoemission data on the layered compound NaCrS2 are presented and related to the electronic structure. The data indicate that the Cr 3d electrons are essentially localised and give rise to a multiplet splitting of the Cr 3s emission line; the magnitude of the splitting is discussed in terms of the magnetic properties of the material and the net spin moment of the Cr ions.
