Strong electronic correlations in a new class of Yb-based compounds: YbXCu/sub 4/ (X = Ag,Au,Pd)

· Phys. Rev. B: Condens. Matter; (United States)
A new series of heavy-electron Yb compounds YbXCu/sub 4/ with X = Ag, Au, or Pd are reported which have electron effective masses as high as --60m/sub e/, where m/sub e/ is the mass of the free electron. Whereas the compounds with X = Au and Pd order magnetically below 1 K, the compound with X = Ag is nonmagnetic. The magnetic susceptibility and specific heat of YbAgCu/sub 4/ can be accounted for by the Bethe-ansatz solution of the Coqblin-Schrieffer impurity model without any adjustable parameters.
