Description
X-ray-absorption fine-structure measurements of the local structure in UCu4Pd are described which indicate a probable lattice-disorder origin for non-Fermi-liquid behavior in this material. Short Pd-Cu distances are observed, consistent with (24±3)% of the Pd atoms occupying nominally Cu sites. A open-quotes Kondo disorderclose quotes model, based on the effect on the local Kondo temperature TK of this interchange and some additional bond-length disorder, agrees quantitatively with previous experimental susceptibility data, and therefore also with specific heat and magnetic resonance experiments. copyright 1998 The American Physical Society
