Results of resistivity, magnetization and susceptibility measurements are reported on U66T34 where T denotes Fe, Co, or Ni. Magnetic susceptibility data on each of the alloys displayed thermomagnetic-history effects indicating some spin-glass like character. The high-field magnetization data showed a significant non-linearity indicating a contribution to the magnetization from a cluster term. The evidence suggests that these alloys form cluster glasses in which only those T atoms whose local environment is sufficiently dense in T atoms bear a stable magnetic moment.
