Abstract

Magnetotransport effects have been investigated in polycrystalline samples of U₆Co and U₆Fe. The superconducting state data have been obtained in applied magnetic fields up to 9 T. U₆Co has a residual resistance ratio RRR(RT/4.2 K) = 2, T_c = 2.44 K and ΔT_c (10%-90%) = 105 mK. The U₆Fe sample has RRR = 7, T_c = 3.95 K and ΔT_c =40 mK. The magnetic thresholds are roughly the same either with the electrical contacts in the Hall configuration or in the resistivity configuration for the U₆Co sample, but they are clearly different for the U₆Fe sample, with the Hall thresholds lying below resistivity thresholds, similar to previous results for UBe₁₃obtained using the same technique.
