Superconducting critical fields of diamond-like films containing tungsten

The superconducting critical fields H c2 of a some diamond-like films incorporating tungsten (W x C 1− x Si, 0.22 <x< 0.28) having critical temperatures between 2 and 4 K have been determined from resistivity measurements. For the field perpendicular to the film H c2 increases continuously as...

Summary:The superconducting critical fields H c2 of a some diamond-like films incorporating tungsten (W x C 1− x Si, 0.22 <x< 0.28) having critical temperatures between 2 and 4 K have been determined from resistivity measurements. For the field perpendicular to the film H c2 increases continuously as the temperature is decreased. At the lowest temperatures, the critical fields are greater than those expected for a normal type II superconductor. The probable origin of this effect lies in the amorphous nature of the films.
