We investigate the spatial distribution of spin/charge current in a nonlocal geometry of a magnetic nanostructure with PyICu and CuPt contacts and analyze the spin Hall effects by applying finite element method in three dimensions. We find that the inhomogeneous current distribution appears in the CuPt connection area, suggesting the possibility of the spin-signal enhancement by controlling the contact shape and the width of the electrodes. The calculated spin Hall voltage is consistent with the experimentally observed Hall resistance.
