Previous electrical resistivity {rho}T, magnetic susceptibility {chi}T, and specific heat C(T) measurements on the Y{sub 1-x}U{sub x}Pd{sub 3} system have revealed Kondo behavior for 0 < {times} < 0.2 and spin-glass-like behavior for 0.3 < {times} < 0.5. The Kondo behavior is unusual and characterized by non-Fermi liquid behavior at low temperatures T {much_lt} T{sub K}, where T{sub K} is the Kondo temperature: {rho}T/{rho}(0) {approximately} 1 {minus} T/(aT{sub K}), and C(T)/T {approximately} 1 {minus} (1/T{sub K})1nT with evidence for a finite T = 0 residual entropy S(0) = (R/2)1n(2). We report measurements of {rho}T, {chi}T, and C(T) on the Sc{sub 1-x}U{sub x}Pd{sub 3} system which reveal similar Kondo, non-Fermi liquid, and spin-glass behaviors.
