Density of states in spin-valve structure with superconducting electrodes
D. Gusakova, A. Vedyayev, O. Kotel'nikova
Abstract
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.
