Spin-polarized triplet supercurrent in Josephson junctions with perpendicular ferromagnetic layers

Autor: Norman O. Birge, Joseph A. Glick, William P. Pratt, Demet Korucu, Reza Loloee, Victor Aguilar

Josephson junctions containing three ferromagnetic layers with non-collinear magnetizations between adjacent layers carry spin-triplet supercurrent under certain conditions. The signature of the spin-triplet supercurrent is a relatively slow decay of
