Character of valence-band states in the Kondo surface alloys CeAgx/Ag(111) and CePt5/Pt(111)
2012
Physical Review B
The crystal and electronic structures of the CePt 5 and CeAg x surface alloys have been investigated by means of low-energy electron diffraction and angle-resolved photoelectron spectroscopy. From measurements performed near the 4d-4f absorption edge we were able to infer the weight of the 4f -electron spectral function with respect to the single-particle density of states. While the typical Kondo features at the Fermi energy (Kondo resonance and spin-orbit partner) in the CePt 5 surface alloy
