Effects of oxygen content on pressure-induced superconductivity in EuMo6S8

  • 1. Tufts University, Medford, Massachusetts 02155

Description

Pressure-induced superconductivity in EuMo6S8 is sensitive to the systematic addition of oxygen. As oxygen content increases, the critical pressure above which the sample is superconducting (Papprox. =11 kbar) decreases, the onset is less abrupt, the maximum T/sub c/ (11.8 K) decreases, and dT/sub c//dP at high pressures (-0.29 K/kbar) is less negative. The c/a ratio and the unit cell volume vary linearly with the extrapolated zero pressure T/sub c/. The results are discussed in terms of an oxygen-induced defect at the Eu site
