The valence transition of 4f electron states in rare-earth compounds is accompanied by a discontinuous change in the Kondo temperature, an energy scale tied to the interaction of the 4f states with the conduction-band states (c-f hybridization). The

The electronic state of single crystals of CeIr2(Zn1−xCdx)20 and CePt2Cd20 has been studied by measuring the electrical resistivity ρ and specific heat C. We found that by substituting Zn with Cd, the lattice parameter expands, and the electronic

This work reports how a hybridization gap develops at valence-transition temperature of a rare-earth compound. The authors show that the gap increases below the transition temperature, along with an energy shift of electron-like conduction band.

We have investigated the electronic structures of Y1-xTmxB6 (x = 0, 0.25) and Yb1-xTmxB6 (x = 0, 0.2) by means of hard x-ray photoemission spectroscopy (HAXPES) at h ν = 5.95 keV. The Tm 3d HAXPES revealed that the valence of Tm in YB6 is ∼2.6 at
