Difficulties of weak localization theory for thin metal films with magnetic impurities

摘要

Magnetoresistance of Au(Fe) films have been measured from 1.5 to 10 K in magnetic fields below 1 T. Two anomalies are found in the interpretation of data based on conventional weak-localization theory. First, there are systematic discrepancies between theoretical curves and experimental data. Second, the spin-orbit scattering rate is temperature dependent. These difficulties are more evident for films with weak disorder. [References: 20]
