The anomalous Hall effect in the perpendicular Ta/CoFeB/MgO thin films

The anomalous Hall effect (AHE) in the perpendicular Ta/CoFeB/MgO thin film has been investigated. Between the AHE coefficient (RS) and longitudinal resistivity (ρxx), a linear behavior of RS/ρxx versus ρxx can be found. Moreover, the conductivity of the film is about 5 × 103 S/cm, which suggests that AHE in the Ta/CoFeB/MgO film be dominated by the intrinsic or scattering-independent mechanism.
