摘要：

Results for the low-temperature magnetoresistance of thin Au films containing similar to 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.
