Triplet superconducting p+ip pairs existing in a graphene sandwiched by superconductor and ferromagnet
چکیده انگلیسی
Since the even-parity (s- or d-wave) superconducting pairs are incompatible with the ferromagnetism, a proper parity for these superconducting pairs existing in the interfaces of superconductors (SCs) and ferromagnets (FMs) should be odd-parity (p-wave). In this study a sandwiched structure constructed by even-parity superconductor/graphene/ferromagnet (ESC/GH/FM) is theoretically proposed to play a role to accommodate stable triplet superconducting pairs in the graphene (GH). The interactions in the graphene induced from the heavy magnetic atoms in FM including Kondo interaction, Kane-Mele and Rashba spin-orbit interactions (SOI) are considered. The calculations reveal a fact that p+ip state in the graphene is stable than pure p state and the former interaction suppress the triplet superconductivity but enhance it by later two SOIs.
