摘要:
The study focused on investigating spin transport in a graphene-based ferromagnet/in-plane exchange field/superconductor junction. It was demonstrated that both the spin-flipped reflection and the anomalous Andreev reflection occur in the junction due to the spin-mixing effect induced by the in-plane exchange field in graphene. The research highlighted that increasing the Fermi energy in the junction can lead to a high level of anomalous Andreev reflection. Furthermore, the study also examined the charge conductance and spin-polarized conductance, showing that these properties are influenced by the strength of the vertical exchange field, the in-plane exchange field, and Fermi energy. The findings of this research could potentially open up new avenues for utilizing graphene in spintronics applications.
