- Аннотация: We investigate the critical temperature Tc of F2F1S trilayers (S is a singlet su- perconductor, F is a ferromagnetic metal), where the long-range triplet supercon- ducting component is generated at noncollinear magnetizations of the F layers [1]. Earlier we demonstrated that Tc in such structures can be a non-monotonic function of the angle alpha between magnetizations of the two F layers [2], contrary to the monotonic Tc(alpha) behavior calculated for the F1SF2 superconducting spin- valve design [3]. It was shown recently [4] the existence of the anomalous depen- dence of the spin-triplet correlations on the angle alpha in FFS structures. We examine the spin-singlet and spin-triplet pairing distributions across the layers and their amplitudes as a function of the angle alpha in the F2F1S и F2SF1 superconducting spin-valve designs to clarify which one and why may show maximum spin-triplet pairing impact on the superconducting Tc.
