Skew scattering and side jump
Webb29 jan. 2024 · In disordered samples though, alternative mechanisms associated with electron scattering off impurities have been suggested: (i) asymmetric electron scattering, called skew scattering, and (ii) a shift of the electron wave packet in real space, called a side jump. It has been claimed that the side jump not only contributes to the VHE but … Webbσ AHE versus σ xx for a variety of materials spanning the various AHE regimes from the side-jump mechanism through the intrinsic and skew scattering regimes (23, 39–43). With an AHE this large, there are few known systems that are comparable to KV 3 Sb 5 .

Webb24 jan. 2001 · Based on the Kubo formalism and on the Dirac equation, this model allows the simultaneous calculation of the skew-scattering and side-jump contributions to the anomalous Hall conductivity. The continuity and the consistency with the weak-relativistic limit described by the Pauli Hamiltonian is shown. For both approaches, Dirac and Pauli, …
WebbThe skew-scattering and the side-jump mechanisms give different contributions to the anomalous Hall resis-tivity. For bulk material, it has been shown that, in certain limits, the skew-scattering contribution is sim-ply proportional to the resistivity14,15 while the side-jump contribution is proportional to the square of the resistivity16. Webb1 jan. 1977 · The scattering asymmetries show up in magnetoresistance and Hall effect experiments and have been mainly studied for rare-earth impurities. They are of interest for determining the anisotropic terms of the conduction electron-impurity interaction, such as quadrupolar Coulomb terms or orbital exchange terms.
Webbthan the skew-scattering (∆yis the length of the side jump as introduced by Berger and lis the mean free path of the conduction electrons). Our observation agrees well with the perception that for dilute magnetic impuri-ties "skew-scattering" is the dominant mechanism and for (disordered) bulk ferromagnetic metals the "side-jump" is dominant ...
