FIG. 1.

Schematic of the sample mounting with an aluminum disk kept a distance away from the superconducting film sample, which rests on a teflon disk. (a) sheet of teflon is inserted on top of the sample, (b) teflon pillars maintain a gap above the sample.

FIG. 2.

m-H curves for the film with teflon sheets of different thickness inserted between the Al-disk and the superconductor, displaying numerous flux jumps over an interval of applied fields. The jumps in the curves are increasingly suppressed as the metal/superconductor distance decreases. The upper panel is a magnified view of the ascending field branch.

Image of FIG. 3.
FIG. 3.

m-H curves for ascending field with the Nb sample and aluminum disk separated by different distances, showing increased suppression of jump activity the smaller their separation becomes.
