Evidence of the side jump mechanism in the anomalous Hall effect in paramagnets
Persistent confusion has existed between the intrinsic (Berry curvature) and the side jump
mechanisms of anomalous Hall effect (AHE) in ferromagnets. We provide unambiguous
identification of the side jump mechanism, in addition to the skew scattering contribution in
epitaxial paramagnetic Ni 34 Cu 66 thin films, in which the intrinsic contribution is by
definition excluded. Furthermore, the temperature dependence of the AHE further reveals
that the side jump mechanism is dominated by the elastic scattering.

Abstract
Persistent confusion has existed between the intrinsic (Berry curvature) and the side jump mechanisms of anomalous Hall effect (AHE) in ferromagnets. We provide unambiguous identification of the side jump mechanism, in addition to the skew scattering contribution in epitaxial paramagnetic Ni 34 Cu 66 thin films, in which the intrinsic contribution is by definition excluded. Furthermore, the temperature dependence of the AHE further reveals that the side jump mechanism is dominated by the elastic scattering.
