Josephson effect between triplet superconductors through a ferromagnetic   barrier of finite width
  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-\pi transitions and for the spin currents, and examine the appropriateness of the common \delta-function approximation for the tunneling region.
