Measurements are reported on the electrical resistivity ρ(B, T) in a wide range of parameters for the heavy-fermion compound UBe13. In addition to known results concerning a very strong dependence of ρ on both magnetic field and temperature, the present results shed new light on the low-temperature, low-field behaviour of the magnetoresistivity Δρ(B, T) = ρ(B, T) - ρ(0, T). As T → 0, Δρ becomes very small, and the results suggest that a change of sign of Δρ from negative to positive takes place below 100 mK. Thus, from the viewpoint of magnetoresistivity, UBe13 appears to behave similarly to the Ce-based heavy-fermion compounds CeAl3 and CeCu2Si2, though important differences remain.
