Measurements on the proximity effect magnetoresistance (MR) of short and narrow gold wires were analyzed. The samples were produced by multilevel electron beam lithography techniques on oxidized silicon substrates. At low magnetic fields, the MR of the wire was observed to be quadratic with resistance increasing rapidly to its nominal state value within ≃ 7 G. Results showed that the relevant length scale determining Aharonov-Bohm-type interference in proximity coupled normal metals was the electron phase coherence length.
