Study of fermi level shifts in al-mn alloys by x-ray absorption-spectroscopy

Abstract

The present authors have studied the Mn K absorption discontinuity in manganese and in two aluminium alloys of compositions AI-14.3 at.percent Mn and AI-30 at.percent Mn. It is found that the K absorption discontinuity of manganese shifts towards high energies for alloys with respect to that for the metal. The results are discussed on the basis of the rigidband model.
