Abstract
Сritical temperatures of multilayer structures of the superconductor/ferromagnet/ferromagnet (S/F/F) type are obtained using the matrix method for solving the linearized Usadel equations. The influence of an additional superconductor layer on the effects of a three-layer spin valve is considered. The possibility of increasing the efficiency of the spin valve modes with an additional superconducting layer S in the place of the layer N is discussed in comparison with an additional normal layer in the S/F/N/F structure.
