Anomalous Hall effect in magnetic disordered alloys: Effects of spin orbital coupling
2013
For disordered ternary Fe0.5(Pd1−xPtx)0.5 alloy films, the anomalous Hall effect obeys the conventional scaling law ρAH=aρxx+bρxx2 with the longitudinal resistivity ρxx and anomalous Hall resistivity ρAH. Contributed by the intrinsic term and the extrinsic side-jump one, the scattering-independent anomalous Hall conductivity b increases with increasing Pt/Pd concentration. In contrast, the skew scattering parameter a is mainly influenced by the residual resistivity. The present results will facilitate the theoretical studies of the anomalous Hall effect in magnetic disordered alloys.
