Superharmonic long-range triplet current in a diffusive Josephson
junction [PDF]
Caroline Richard, Manuel Houzet, Julia S. MeyerWe study the Josephson current through a long ferromagnetic bilayer in the diffusive regime. For non-collinear magnetizations, we find that the current-phase relation is dominated by its second harmonic, which corresponds to the long-range coherent propagation of two triplet pairs of electrons.View original: http://arxiv.org/abs/1303.1022
