Query: Measurement of the full distribution of the persistent current in
  normal-metal rings   We have measured the persistent current in individual normal metal rings over
a wide range of magnetic fields. From this data, we extract the first six
cumulants of the single-ring persistent current distribution. Our results are
consistent with the theoretical prediction that this distribution should be
nearly Gaussian (i.e., that these cumulants should be nearly zero) for
diffusive metallic rings. This measurement highlights the particular
sensitivity of persistent current to the mesoscopic fluctuations within a
single coherent volume.
