Description

YB LIII X-ray absorption edge measurements yielded 2.20+ and 2.50+ for the Yb valence in the Yb-Rh-Sn compounds with phase I and II', respectively. The former is superconducting (Tc≅8 K), and contains only one crystallographic site for Yb, which suggests that this atom is in a valence fluctuation state. (orig.)
