Abstract

We study theoretically the effect of Andreev reflection in ferromagnet/superconductor/ferromagnet structures. The spin-polarized quasiparticle current penetrates to the superconductor in the range of penetration depth from the interfaces, and thus the current depends on the relative orientation of magnetization of the ferromagnets. We show that the current is controlled by the Andreev reflection at the interfaces.
