Abstract

Working with epitaxial films of Fe, we succeeded in independent control of different scattering processes in the anomalous Hall effect. The result clearly exposed the fundamental flaws of the conventional scaling \ensuremathρAH=f(\ensuremathρxx) between the anomalous Hall resistivity and longitudinal resistivity. A new scaling \ensuremathρAH=f(\ensuremathρxx0,\ensuremathρxx) that also involves the residual resistivity has been established which helps identify the intrinsic and extrinsic mechanisms of the anomalous Hall effect.
