Abstract

The effect of interfacial scattering on anomalous Hall effect (AHE) was studied in the (Ni_{36/n nm}/Au_{12/n nm})_n multilayers. Field-dependent Hall resistivity was measured in the temperature range of 5-300 K with the magnetic field up to 50 kOe. The anomalous Hall resistivity (P_AHE) was enhanced by more than six times at 5 K from n = 1 to n = 12 due to the increased interfacial scattering, whereas the longitudinal resistivity (P_xx) was increased nearly three times. A scaling relation P_AHE ∼ P_xx^γ with γ = 1.85 was obtained for P_AHE and P_xx measured at 5 K, indicating that the dominant mechanism(s) of the AHE in these multilayers should be side-jump or/and intrinsic in nature. The new scaling relation P_AHE = αP_xx0 + βP_xx0² + bP_xx² (Tian et al 2009 Phys. Rev. Lett. 103 087206) has been applied to our data to identify the origin of the AHE in this type of multilayer.
