title = "High- and Low-Energy Photoemission Study of Strongly Correlated Au–Ga–Ce Quasicrystal Approximants: Localized 4f Nature and Disorder Effects",
abstract = "We have investigated the electronic structures of Ce-based 1=1 quasicrystal approximants Au59.2Ga25.7Ce15.1 and Au60.3Ga26.1Ce13.6 by hard X-ray photoemission (HAXPES) and high-resolution photoemission spectroscopy. The localized Ce 4 f electronic states are revealed for both Au–Ga–Ce approximants. Moreover, disorders in the compounds notably affect their electronic states, which has been detected by the core-level HAXPES. Valence-band photoemission spectra show the slight spectral difference depending on the composition ratio, which can be explained by a rigid-band-like shift.",
