ABSTRACTWe report here the results obtained for the valence band of four compounds from the Al-Cr-Fe system, all being approximants of the decagonal quasicrystalline phase as probed by a combination of X-ray emission and X-ray photoemission spectroscopy techniques. Salient features are d-d and p-d hybridizations at the Fermi level and in its close vicinity as well as a repulsive interaction between the d states of the two transition elements. Within about 4 eV below the Fermi level Al states are suggested to be of more localized-like character in the Al-Cr-Fe samples than in Al-Cu-Fe ones.
