The electronic structure of the Co
ZrSn Heusler alloys has been
studied by X-ray photoelectron spectroscopy (XPS).
XPS valence band spectra can be compared with ab initio electronic structure
calculations using the linearized muffin-tin orbital (LMTO) method.
The calculated magnetic moments per Co atom agree well with the moments obtained
from experiment. The LMTO calculations also show
the energy shifts of the Co, Zr and Sn valence electron
states towards the Fermi level when the concentration of vacancies increases
in these alloys.
