Abstract

The spatial distribution of the spin current in the nonlocal geometry of a contact between nonmagnetic and ferromagnetic metals was discussed. The finite size effect of the contact area was also considered, by applying finite element method in two dimensions. It was found that by using the tunneling contacts, the spin accumulation was improved. Based on the one-dimensional model, the spin accumulation signal in the nonlocal geometry was evaluated. The two-dimensional inhomogeneous current distribution was observed in contact area, when the contacts were tunneling-like.
