High-field magnetoresistivity (MR) measurements are presented for high-purity samples of TiBe/sub 2/ and UAl/sub 2/. The MR of TiBe/sub 2/ gives strong evidence for scattering due to spin fluctuations. The peculiar features in the MR around 5 T are apparently connected to the maxima in the susceptibility and may provide a clue to a theoretical description of the contributions of spin fluctuations to the resistivity. A value for the spin-fluctuation temperature is obtained and it is in agreement with earlier estimates. The MR of UAl/sub 2/ is consistent with the behavior of a compensated metal. From the high-field behavior of the MR we expect to observe de Haas--van Alphen oscillations above approximately 10 T, but up to 40 T no signals are found. A small negative MR at higher temperatures may be due to spin-fluctuation scattering, but the evidence is not as clear as for TiBe/sub 2/.
