X-ray absorption near-edge fine structure (XANES) and valence-band photoelectron spectroscopy (PES) measurements were performed to elucidate the effect of the Mn constituent on the electronic structures of icosahedral (i)-Al70Pd22.5(Re1−xMnx)7.5 quasicrystals (QCs). Pd and Re L3-edge and Al K-edge XANES spectra reveal that the unoccupied Pd 4d, Re 5d and Al 3p states are insensitive to the Mn doping. The valence-band PES and resonant photoemission analysis indicate a marked Mn 3d contribution within ~5 eV of the Fermi level, suggesting that the Mn doping increases the conductivity of i-Al–Pd–Re–Mn QCs.
