Abstract

Critical currents in a sputtered Chevrel-phase copper molybdenum sulphide have been measured at 4.2 K as a function of applied magnetic field. Self-field critical-current values up to 10⁹ A/m² were found, decreasing to 10⁸ A/m² at 3 T. Graphs of pinning forces versus field were found to be independent of field direction, and the pinning mechanism is sample independent. Critical-current densities for sputtered lead molybdenum sulphide are estimated to be ≳10⁸ A/m² at 26 T based on a scaling law for pinning.
