摘要：
We investigate superconductor (S) and ferromagnetic metal (F) SFF structures with noncollinear magnetizations of F films with arbitrary FF interface transparency. We show the existence of phase slips at both the SF and FF interfaces, which manifest themselves in the anomalous dependence of the spin-triplet correlations on the misorientation angle between the magnetization vectors in the F layers. We discuss how these effects can be observed in experiments with Josephson pi junctions.
