Abstract

We have measured the temperature and magnetic field dependence of the low temperature resistivity of Au wires with dilute (∼50 ppm) Fe impurities as a function of wire width. In contrast to previous experiments, we find an increase in slope of the temperature dependent resistivity Δρ{variant}(T) as the wire width is decreased. A systematic trend is also evident in the field dependent resistivity Δρ{variant}(H). We also find an unusual scaling relation between Δρ{variant}(T) and Δρ{variant}(H) in our wider samples.
