Abstract
The electronic structure of the Co2-xZrSn Heusler alloys has been studied b y X-ray photoelectron spectroscopy (XPS). XPS valence band spectra can be c ompared with ab initio electronic structure calculations using the lineariz ed muffin-tin orbital (LMTO) method. The calculated magnetic moments per Co atom agree well with the moments obtained from experiment. The LMTO calcul ations also show the energy shifts of the Co, Zr and Sn valence electron st ates towards the Fermi level when the concentration of vacancies increases in these alloys.
