Low-frequency ac currents have been observed to induce a dc voltage {ital V}{sub dc} across macroscopic percolating films of lead and aluminum in the vicinity of their superconducting transition. This conversion is observed down to a frequency of 10 Hz, which rules out an inverse-Josephson-effect interpretation. {ital V}{sub dc} shows sharp oscillations as a function of a magnetic field. This pattern dependence on the angle between the sample and the applied field identifies these oscillations as an Aharonov-Bohm effect.
