摘要: The spin-polarized transport properties of a high-spin-state spin-crossover molecular junction with zigzag-edge graphene nanoribbon electrodes have been studied using density functional theory combined the nonequilibrium Green's-function formalism. presents integrated spintronic functionalities such as negative differential resistance behavior, spin filter and rectifying effect, associated giant magnetoresistance effect by tuning external magnetic field. Furthermore, are almost unaffected electrode temperature. microscopic mechanism these is discussed. These results represent step toward multifunctional devices on level individual molecule.
