title: Absolute spin-valve effect with superconducting proximity structures.
abstract: We investigate spin-dependent transport in hybrid superconductor-normal-metal-ferromagnet structures under conditions of the proximity effect. We demonstrate the feasibility of the absolute spin-valve effect for a certain interval of voltages in a system consisting of two coupled trilayer structures. Our results are also valid for noncollinear magnetic configurations of the ferromagnets.
