Abstract

In this paper, spin-switch effect under the influence of anisotropic pairing symmetry is investigated. It is shown that the non-local conductance is sensitive to the exchange splitting, the incident energy, and the orientation of the superconducting gap. With the increase of the exchange splitting from zero to Fermi energy, the crossed Andreev reflection conductance for parallel configuration of magnetization and the elastic co-tunneling conductance for antiparallel configuration of magnetization are suppressed to a vanishing value. When the exchange splitting equates to Fermi energy, for values of the orientation of d-wave superconducting gap in the k-space very close to π / 4, magnitude of the spin-switch effect is suppressed completely. Moreover, in contrast to the single graphene-based ferromagnet/superconductor junction case, a π / 2 periodic oscillatory behavior about the barrier is observed directly in the present spin valve. The physical origination for those phenomena has also been analyzed.
