We study the superconducting transition temperature Tc of F2/F1/S trilayers (Fi is a metallic ferromagnet, S is a s-superconductor), where the long-range triplet superconducting component is generated at canted magnetizations of the F layers. In this paper we show that it is possible to realize different spin-valve effect modes - the standard switching effect, the triplet spin-valve effect, reentrant Tc(α) dependence or reentrant Tc(α) dependence with the inverse switching effect - by variation of the F2/F1 interface transparency or the exchange splitting energy. In addition, we show that positionof the Tc minimum can be changed by joint variation of the F2/F1 interface transparency and the layerthicknesses.
С помощью матричного метода решения линеаризованных уравнений Узаделя получены критические температуры многослойных структур вида сверхпроводник / ферромагнетик / ферромагнетик (S/F/F). Рассмотрено влияние дополнительного слоя сверхпроводника на эффекты трехслойного спинового вентиля. В сравнении с дополнительным нормальным слоем в структуре S/F/N/F, обсуждена возможность увеличения эффективности режимов спинового вентиля с дополнительным сверхпроводящим слоем S на месте слоя N.
