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 … Webb9 feb. 2024 · The details of the model we used are described in the subsequent section. In the “Skew scattering” section, we show how scattering by noncoplanar magnetic texture leads to skew scattering. An explicit formula for Hall conductivity is given in the “Boltzmann theory” section using the result we obtained in the “Skew scattering” section.

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. Webb15 sep. 2024 · We find that the skew scattering and the side jump coming from static scattering sources have noticeable changes due to the δ-doping of Bi while the intrinsic contribution of the AHE and the side jump contributions coming from dynamic scattering sources are robust despite of the strong SOC of Bi impurities. 2.
