Electron structure and atomic magnetic moments of Fe-Cr alloys based on X-ray photoelectron spectroscopy and calculations in the coherent-potential approximation

Abstract Studies of the electron and magnetic atomic states of Fe-Cr alloys were carried out by means of X-ray photoemission spectroscopy and theoretical calculations. Exchange splitting measurements for 3s spectra were used to estimate the atomic magnetic moment of transition metals and Fe-Cr alloys. The concentration dependence of the calculation in the two-band s-d coherent-potential approximation of the charge transfer and magnetic moment agrees well with experimental data.
