  We discuss a model of Ferromagnet / Superconductor / Ferromagnet (FSF) double
junction in which the quasiparticles are not in equilibrium with the condensate
in a region of the superconductor containing the two FS contacts. The role of
geometry is discussed, as well as the role of a small residual density of
states within the superconducting gap, that allows a sequential tunneling
crossed current. With elastic quasiparticle transport and the geometry with
lateral contacts, the crossed conductances in the sequential tunneling channel
are almost equal in the normal and superconducting phases, if the distance
between the FS interfaces is sufficiently small. The sequential tunneling and
spatially separated processes (the so-called crossed Andreev reflection and
elastic cotunneling processes) lead to different signs of the crossed current
in the antiparallel alignment for tunnel interfaces.
