Abstract: Working with epitaxial films of Fe, we succeeded in independent control ofdifferent scattering processes in the anomalous Hall effect. The resultappropriately accounted for the role of phonons, thereby clearly exposing thefundamental flaws of the standard plot of the anomalous Hall resistivity versuslongitudinal resistivity. A new scaling has been thus established that allowsan unambiguous identification of the intrinsic Berry curvature mechanism aswell as the extrinsic skew scattering and side-jump mechanisms of the anomalousHall effect.
