Abstract
Charge and spin transport in a junction involving two triplet superconductors and a ferromagnetic barrier are studied. We use Bogoliubov–de Gennes wavefunctions to construct the Green’s function, from which we obtain the Josephson currents in terms of the Andreev reflection coefficients. We focus on the consequences of a finite barrier width for the occurrence of 0–π transitions and for the spin currents, and examine the appropriateness of the common δ-function approximation for the tunneling region.
