Electronic spin precession in graphene-based superlattice with periodical gate and magnetic modulation

► The efficient exchange field can induce a spin precession. ► The spin precession is complete isoamplitude for the case of the normal incidence. ► For inclined incidence, precession disappears in a certain range of efficient exchange field. ► The superlattice configuration may revive the disappeared precession. ► But the superlattice configuration can suppress the electronic transport.
