Abstract

We report that the inhomogeneous spin accumulation in a nonmagnetic layer induces the spin-polarized current flowing in a detector ferromagnetic strip lying underneath the nonmagnetic layer. In Ni-FeCu planar spin-valve structures, the induced spin-polarized current causes the spin-valve-like signal in the Ni-Fe wire without any boundary resistance in the CuNi-Fe junction. The relation between the inhomogeneous spin accumulation and the magnitude of the induced spin-valve-like signal is investigated by varying the width of the Cu wire.
