Effects Of Surface And Interface Scattering On Anomalous Hall Effect In Co/Pd Multilayers

In this paper, we report the results of surface and interface scattering on anomalous Hall effect in Co/Pd multilayers with perpendicularmagnetic anisotropy. The surface scattering effect has been extracted from the total anomalous Hall effect. By scaling surface scattering contribution with rho(AHs) similar to rho(gamma)(ss), the exponent gamma has been found to decrease with the increase of surface scattering resistivity, which could account for the thickness-dependent anomalous Hall effect. Interface diffusion induced by rapid thermal annealing modifies not only the magnetization and longitudinal resistivity but also the anomalous Hall effect; a large exponent gamma similar to 5.7 has been attributed to interface scattering-dominated anomalous Hall effect.
