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.Keywords
