Long-range odd triplet superconductivity in SF structures with Neel walls

arXiv:cond-mat/0507396 · doi:10.1103/PhysRevB.72.184504

Abstract

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 ξ_T = \sqrt{D/2πT} (in the dirty limit). The density of states variation in the domains due to this component changes over distances of the order ξ_T and turns to zero in the middle of domains if the magnetization rotates in the same direction in all domain walls.
