摘要：
We study the spatial distribution of spin/charge current in the nonlocal geometry of the Py/Cu/Pt nanostructure, where the Py/Cu and Cu/Pt structures are employed as a spin injection/accumulation and a spin/charge current converter, respectively, by applying a finite element method in three-dimensions. Calculating two types of the device operations, we have found that the inhomogeneous current distribution appears in Cu/Pt area, suggesting the possibility of the spin-signal enhancement by controlling the shape of the Cu/Pt structure
