✦ Synopsis

Previous electrical resistivity piT), magnetic susceptibility x(T), and specific heat C(T) measurements on the Yl-xUxPd3 system have revealed Kondo behavior for 0 < x~<0.2 and spin-glass-like behavior for 0.3~<x ~<0.5. The Kondo behavior is unusual and characterized by non-Fermi liquid behavior at low temperatures T <~ TK, where TK is the Kondo temperature: p(T)/pI0) ~, ! -T/(aTK) and C(T)/T ,~ -(1/TK)ln Twith evidence for a finite T = 0 residual entropy S(0) = (R/2)ln (?~. We report measurements of p(T), 7,(T), and CI T) on the Sc~., UxPd3 system which reveal similar Kondo, non-Fermi liquid, and spin-glass behaviors.
