Josephson effect between triplet superconductors through a ferromagnetic barrier of finite width

摘要: Institut fu¨r Theoretische Physik, Technische Universit¨at Dresden, 01062 Germany(Dated: September 27, 2011)Charge and spin transport in a junction involving two triplet superconductors ferromagneticbarrier are studied. We use Bogoliubov-de Gennes wavefunctions to construct the Green’s function,from which we obtain Josephson currents terms of Andreev reflection coefficients. Wefocus on consequences finite barrier width for occurrence 0-π transitions thespin currents, examine appropriateness common δ-function approximation thetunneling region.
