UAl/sub 2/ is thought to exhibit ferromagnetic spin fluctuations. We have studied the electrical resistivity of alloys of UAl/sub 2/ with U replaced by Sc, Y, Zr, La, Ce, or Lu. We find that the spin-fluctuation T/sup 2/ law at low temperatures changes to a T/sup 3/2/ law with substitution. We also find an unusually large (approx. 10 ..mu cap omega.. cm/at. %) rise in the residual resistivity in these alloys. Both of these effects are independent of substituent and thus must be due to the unusual properties of UAl/sub 2/. We attribute these effects to f-bond breaking by these substitutions.
