    Thermoelectric effects in a double-dot Aharonov-Bohm interferometer with Rashba spin-orbit interaction

    We investigate the thermoelectric effects in a double-dot Aharonov-Bohm interferometer coupled to ferromagnetic leads held at different temperatures. The interplay of Rashba spin-orbit interaction (RSOI) and ...

    Supercurrent switching effect in zigzag graphene nanoribbons

    The non-equilibrium Green’s function approach is applied to investigate dc Josephson currents in S/ZGNR/S junctions, where ZGNR is the zigzag graphene nanoribbon and S is the s-wave superconductor. If the mid...

    Spin filter effect and large magnetoresistance in the zigzag graphene nanoribbons

    The spin filter effect and magnetoresistance (MR) in the graphene nanoribbons with zigzag edges have been investigated by the non-equilibrium Green’s function method. Due to the spin-dependent current blocking...

    Spin transport in magnetic graphene superlattices

    We study spin transport in normal/ferromagnetic/normal/ferromagnetic.../normal graphene superlattices, which can be realized by putting a series of magnetic insulator bars on top of a graphene sheet. Owing to ...

    Triplet pairing states with equal spins in ferromagnet/superconductor heterojunctions for noncollinear magnetizations

    Four-component Bogoliubov-de Gennes equations are applied to study tunneling conductance spectra of ferromagnet/ferromagnet/d-wave superconductor (F1/F2/d-wave S) tunnel junctions and to find out signs of spin-tr...
