Abstract

The variation of the electrical resistanceR of EuMo6S8 with temperatureT and applied magnetic fieldH was determined at pressuresP 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 ofR onT andH. AtP=8.5 kbar, the magnetoresistance is determined by the freezing out of the Eu2+ spins asH increases. ForP>13 kbar, EuMo6S8 exhibits bulk superconductivity, and we investigated the upper critical magnetic fieldHc2(T). The analysis of these results shows that our EuMo6S8 samples are clean superconductors. We observe thatHc2 is strongly reduced by pressure, perhaps due to an increase of the carrier concentration with pressure.
