The variation of the electrical resistance R of EuMo/sub 6/S/sub 8/ with temperature T and applied magnetic field H was determined at pressures P to 19 kbar. At ambient pressure, the results are in agreement with previous work on samples of similar quality, where it was determined that variations of the carrier concentration were responsible for the very strong dependence of R on T and H. At P = 8.5 kbar, the magnetoresistance is determined by the freezing out of the Eu/sup 2 +/ spins as H increases. For P > 13 kbar, EuMo/sub 6/S/sub 8/ exhibits bulk superconductivity, and the authors investigated the upper critical magnetic field H/sub c2/(T). The analysis of these results shows that their EuMo/sub 6/S/sub 8/ samples are clean superconductors. They observe that H/sub c2/ is strongly reduced by pressure, perhaps due to an increase of the carrier concentration with pressure.
