Using the matrix method for solving linearized Usadel equations in the multimode approximation, the critical temperatures of the multilayer structures of the Superconductor / Ferromagnet / Ferromagnet (S/F/F) type has been obtained. The influence of an additional superconductor layer on the effects of the three-layer spin valve has been considered. In comparison with the additional normal layer in an S/F/N/F structure, the possibility of increasing the efficiency of the spin valve modes in a structure with an additional superconducting layer S instead of N has been discussed.
