High energy, high resolution photoelectron spectroscopy of Co2Mn1−xFexSi

This work reports on high resolution photoelectron spectroscopy for the valence band of Co2Mn1-xFexSi (x = 0,0.5,1) excited by photons of about 8 keV energy. The measurements show good agreement with calculations of the electronic structure using the LDA + U scheme. It is shown that the high energy...

Summary:This work reports on high resolution photoelectron spectroscopy for the valence band of Co2Mn1-xFexSi (x = 0,0.5,1) excited by photons of about 8 keV energy. The measurements show good agreement with calculations of the electronic structure using the LDA + U scheme. It is shown that the high energy spectra reveal the bulk electronic structure better compared with low energy x-ray photoelectron spectroscopy spectra. The high resolution measurements of the valence band close to the Fermi energy indicate the existence of the gap in the minority states for all the three alloys.
