摘要：

Low-energy excited photoemission spectra of YbXCu4 (X = Cd, Mg, Zn) with high-energy resolution have been measured, in comparison with those of the valence transition compound YbInCu4. The energy position of the peak due to the conduction-band states hybridized with the Yb2+ 4f(7/2) states, qualitatively reflects the X-dependent Kondo temperature. A comparison between the PES spectra of YbInCu4 and YbCdCu4, suggests the In 5p states play an important role for the valence transition of YbInCu4. (c) 2005 Elsevier B.V. All rights reserved.
