A brief review of experimental results which reveal non-Fermi-liquid behavior in the low temperature properties of the M{sub 1-x}U{sub x}Pd{sub 3} (M = rare earth or Th) Kondo alloy system is presented. Measurements of lattice parameters, electrical resistivity, magnetic susceptibility, low temperature specific heat, and magnetic neutron scattering are compared to predictions of the multichannel Kondo model, and are generally consistent with a two-channel spin-1/2 quadrupoler Kondo effect. Possible deviations from the model due to crystalline electric field effects, interionic interactions, disorder, and Fermi-level tuning aspects are discussed.
