Long-Range Triplet Supercurrents Induced by Singlet Supercurrents Parallel to Magnetic Interfaces

Abstract

Employing a spin-parameterized Kleldysh-Usadel technique for the diffusive regime, we demonstrate that even in the low proximity limit, considerable long-ranged triplet supercurrents can be effectively generated by spin-singlet supercurrents flowing \textit{parallel} to the interfaces of uniform double ferromagnet interlayers with noncollinear exchange fields "{\it independent}" of actual junction geometry. The triplet supercurrents are found to be most pronounced when the thicknesses of the ferromagnet strips are unequal. To experimentally verify this generic phenomenon, we propose an accessible and well-controlled structure that can fully isolate the long-range triplet effects.
