Upper critical fields of some ternary molybdenum sulphides

Abstract
The upper critical fields of some ternary molybdenum sulphides are found to be extremely high. Extrapolations to low temperatures indicate values above 500 kG for CuMo3S4, SnMo5S6, Pb0.9Mo5.1S6 and SnAl0.5Mo5S6 samples with Tc approximately=14 K.
