Spin accumulation in magnetic tunnel junctions and lateral all-ferromagnetic spin valves is theoretically investigated by using a spin-dependent diffusive transport model. When electric current tunnels through a barrier, spin accumulation occurs in the ferromagnetic layer and can be detected with nonlocal spin valve measurements. Depending on the relative orientation of magnetization, the nonlocal spin signal has three different values and can determine the bulk spin polarization of the ferromagnetic material.
