title: Transport properties in ferromagnetic Josephson junctions between triplet superconductors.
abstract: Charge and spin Josephson currents in a ballistic superconductor-ferromagnet-superconductor junction with spin-triplet pairing symmetry are studied using the quasiclassical Eilenberger equation. The gap vector of superconductors has an arbitrary relative angle with respect to magnetization of the ferromagnetic layer. We clarify the effects of the thickness of the ferromagnetic layer and the magnitude of the magnetization on the Josephson charge and spin currents. We find that the 0-π transition can occur when the misorientation angle between the exchange field of the ferromagnetic layer and the d-vector is smaller than π/4. We also show how spin current flows due to misorientation between the exchange field and the d-vector.
