Description
YbInCu4 undergoes a first-order isostructural valence transition near 40 K, whereas YbAgCu4 is a moderately heavy (γ=250 mJ/molK2) mixed-valence compound. We have succeeded in growing single crystals of these compounds, as well as many intermediate alloys, using flux-growth techniques. The evolution from YbInCu4 to YbAgCu4 has been characterized using electrical resistivity, magnetic susceptibility, and x-ray powder diffraction. The data are interpreted in terms of the evolution of the single-impurity Kondo temperature as a function of Ag concentration. copyright 1996 The American Physical Society
