Abstract
Low-temperature transport properties in a ferromagnetic Fe 19Ni81 nanoring were studied. In the nanoring, resistance oscillation due to the Aharonov-Bohm effect of a conduction electron was observed. However, the reproducibility of resistance with magnetic field, which is usually observed in non-magnetic metals, was not observed. This result suggests that some kinds of degrees of freedom, which persist even at low temperature break in part the reproducibility of the aperiodic fluctuation in magnetoresistance.
