Abstract

Magnetic susceptibility studies of the sharp Yb²⁺→Yb³⁺ valence phase transition in Yb_xR_yIn_1-x-yCu₂, cubic Laves phase systems, are reported. Whenever the substitute ion R is larger than Yb or In, R = Sn, La, Eu, the valence transition temperature, T_v, increases. Smaller ions, R = Y, Lu, Ga, decrease T_v. This is consistent with the expectation for strong correlation between valence and available volume.
