- 論文の詳細を見る
By combining the high resolution hard and soft X-ray photoelectron spectroscopy, the Yb 3d and 4f states in the strongly correlated electron system, YbInCu4, are studied. After high accuracy experimental determination of the four unknown physical quantities such as the valence values and thicknesses of the surface and sub-surface regions, genuine behaviors of the Kondo resonance as well as the electronic structures in the bulk and sub-surface are clarified. A clear first order valence transition in the bulk and a gradual valence change in the sub-surface region with temperature are revealed.
