【 摘 要 】

We consider a multidomain superconductor/ferromagnet (SF) structure with an in-plane magnetization, assuming that the neighboring domains are separated by the Neel domain walls. We show that an odd triplet long-range component arises in the domain walls and spreads into domains over a long distance of the order xi(T)=root(D/2 pi T) (in the dirty limit). The density of states variation in the domains due to this component changes over distances of the order xi(T) and turns to zero in the middle of domains if the magnetization rotates in the same direction in all domain walls.
