Observation of he aharonov-bohm oscillations in normal-metal rings
Abstract
Magnetoresistance oscillations periodic with respect to the flux he have been observed in submicron-diameter Au rings, along with weaker h2e oscillations. The he oscillations persist to very large magnetic fields. The background structure in the magnetoresistance was not symmetric about zero field. The temperature dependence of both the amplitude of the oscillations and the background are consistent with the recent theory by Stone. © 1985 The American Physical Society.
