Critical currents in the Chevrel-phase lead molybdenum sulfide thin films

Abstract

Critical currents in thin films of Chevrel-phase lead molybdenum sulfide have been measured as a function of applied magnetic field up to 8.5 T. The magnetic field was perpendicular or parallel to the film plane, and a 5-μV/cm criterion was used to define the critical current density Jc. The maximum value of critical current density was above 106 A/cm2 at zero field and 5×104 A/cm2 at 8 T. These values are greater than the best reported so far.
