Summary

THE AUTHORS HAVE MEASURED THE MAGNETORESISTANCE OF THIN FILMS OF THIS SUPERCONDUCTOR TILL 20 T. THEY CONSIDER THE RESULTS OBTAINED IN A MAGNETIC FIELD PERPENDICULAR TO THE PLANE OF THIS FILM. ABOVE A CRITICAL TEMPERATURE EQUAL TO 88 K, MAGNETORESISTANCE IS LINKED TO THE PRESENCE OF TWO-DIMENSIONAL SUPERCONDUCTING FLUCTUATION. BELOW THE CRITICAL TEMPERATURE, MAGNETORESISTANCE FOLLOWS A SCALING TEMPERATURE, TOTALLY DIFFERENT FROM THE BEHAVIOUR DUE TO A FLUX-LINE MOTION, WITH H HAVING THE SAME FUNCTIONAL DEPENDENCY AS T SUPERIOR TO THE CRITICAL TEMPERATURE.
