Abstract

Results for the low-temperature magnetoresistance of thin Au films containing \ensuremath{\sim}30 ppm Fe are reported. As expected, we observe contributions from both the classical magnetoresistance and the local magnetic moments (i.e., the Fe). The local-moment magnetoresistance is a strong function of film thickness, and is suppressed as the thickness is reduced. This finding is compared with previous results for the Kondo effect in small systems, and with recent theoretical predictions. \textcopyright{} 1996 The American Physical Society.
