The anomalous Hall effect in ferromagnetic Fe: Skew scattering or side jump?

The question is investigated whether the anomalous Hall effect (AHE) in Fe films is due to skew scattering or side jump. For this purpose sandwiches of FeIn are investigated in which the conduction electrons carry their drift velocity across the interface. This yields an additional AHE conductance $\Delta G_{xy}$ whose dependence on the In mean free path is used to determine the mechanism of the AHE in the Fe film. The structure of the Fe film is kept constant.
