Spin polarized electrons injected from ferromagnets (F) into non-magnetic materials (N) create nonequilibrium spin accumulation in N. This spin accumulation can be detected as a voltage signal by using non-local transport measurement for a F/N/F structure with tunnel barriers. We performed non-local measurements for Ni{sub 81}Fe{sub 19}/Al/Ni{sub 81}Fe{sub 19} with double tunnel junctions to confirm the spin accumulation. The spin-dependent signals {delta}R={delta}V/I as large as 35m{omega} were obtained at 10K and decreased with increasing temperature due to the reduction of the spin diffusion length.
