Abstract
The upper critical field of percolating lead films above and below the percolation threshold has been measured by monitoring the samples electrical resistance as a function of an applied magnetic field. We find that it remains constant across the threshold, as predicted by theory based on the fractal nature of the infinite clusters and of large finite clusters.
