- Аннотация: Recent theories developed for weak ferromagnet spin valves predicted that i) SFF configuration is favorable for the observation of the spin valve effect; ii) the behavior of Tc between P and AP configuration is monotonous for FSF structure. Our data shows that both these statements may be not true. To describe this effect we developed theory valid for a strong ferromagnet, like Co. We present theory and transport measurements on Nb/Co based spin-valve systems in which we explore the effect of non-collinear exchange fields on the superconducting state. These results are in strong agreement with theoretical expectations for a suppression of Tc with non-collinearity due to the generation of LRTC.
