Abstract

In order to understand the electric current distribution in a non-local geometry, the geometrical dependence of non-local Hall resistance was investigated for lateral devices consisting of an FePt perpendicular spin polarizer and a Au Hall cross. The finite element simulation was also carried out to calculate the electric potential in the devices. The experiment and the simulation indicated that non-local Hall resistance included the contribution of anomalous Hall effect (AHE) in the FePt perpendicular spin polarizer. The resistance change due to AHE in FePt became remarkable for devices with a wide electrode. Taking into account the contribution of AHE, the spin Hall angle was estimated to be 0.05 for the device with a narrow Au electrode.
