Abstract

We report a systematic study of the face-centered-cubic compounds YbXCu4 (X = Ag, Au, Cd, Mg, Tl, and Zn), as well as their corresponding nonmagneticanalogues LuXCu4. X-ray diffraction, heat capacity, magnetic susceptibility, high-field magnetization, electrical resistivity, Hall effect, and L-III-edge absorption measurements have been performed. The compounds have Kondotemperatures that range from about 10 K to nearly 1000 K. Although the single-impurity Kondo model qualitatively describes the physical properties ofthese materials, the quantitative details are not well described and the quality of the fits varies strongly from compound to compound. Compound-to-compound variations in crystal-electric fields, effective valence, and the strength of f-ligand hybridization effects, as well as the influence of intrinsic disorder, may help to explain these discrepancies.
