  Energy variation of the density of states (DOS) has been calculated in the
superconductor/ferromagnet/ferromagnet/superconductor structure (SFFS) in the
frame of Gorkov equations taking into account the s-d electron scattering in
the ferromagnetic layers. DOS behavior is presented for the antiparallel and
parallel magnetic moments alignment of two adjacent F layers. The cases of
small and large values of exchange ferromagnetic field are discussed.
