  • Title: Giant spin-Hall effect induced by the Zeeman interaction in graphene.
    Author: Abanin DA, Gorbachev RV, Novoselov KS, Geim AK, Levitov LS.
    Journal: Phys Rev Lett; 2011 Aug 26; 107(9):096601. PubMed ID: 21929257.
    Abstract:
    We propose a new approach to generate and detect spin currents in graphene, based on a large spin-Hall response arising near the neutrality point in the presence of an external magnetic field. Spin currents result from the imbalance of the Hall resistivity for the spin-up and spin-down carriers induced by the Zeeman interaction, and do not involve a spin-orbit interaction. Large values of the spin-Hall response achievable in moderate magnetic fields produced by on-chip sources, and up to room temperature, make the effect viable for spintronics applications.
