Abstract

An oscillatory magnetic field dependence of the de voltage Vdc is observed near the percolation threshold upon the passage of a low-frequency current through superconducting Sn–Ge thin-film composites. These oscillations are attributed to the quantum interference effect in a Josephson percolation system. The oscillatory structure of Vdc(H) is of fractal origin. A hypothesis concerning the mechanism responsible for the “1/f noise” is proposed.
