Abstract:
A study of the K X-ray absorption edge of manganese in a series of rapidly quenched substitutional disordered Al-Mn alloys (Al-14.71 at. percent Mn to Al-28 at. percent Mn) is reported. It is observed that the energy of the principal absorption edge of manganese in these alloys does not change significantly with respect to that in the parent ordered phase Al-14-3 at. percent Mn, indicating that there is no appreciable shift in the Fermi level with the addition of manganese atoms to the ordered phase. The results are discussed in the light of the theories proposed by Tamaki et al. and by Stern.
