Abstract

howed that the valence state of Yb is +2.8. The low-temperature dependences of the electrical resistivity and magnetic susceptibility can be adequately described by a T-2 term that supports the Fermi-liquid picture. The Kadowaki-Woods relation gives a low value of the degeneracy (N = 2). (C) 2015 Elsevier B.V. All rights reserved.
