  • Descrição: The article has presented first-principles quantum transport calculations for characterizing spin-dependent transport properties of nanodevices made by iron-phthalocyanine (FePc) molecule sandwiched between two zigzag graphene nanoribbon electrodes. These devices have large magnetoresistance, large spin polarization, dual spin-filtering and negative differential resistance (NDR). The studies have shown that the orbitals symmetry of the energy bands and spin mismatching of the electrons are responsible for the dual spin filtering effect.
