Abstract :
The spin precession in graphene superlattice with periodically modulated electrostatic field and efficient exchange field is investigated theoretically. It is found that the efficient exchange field can induce a spin precession, which is different from the case of the Rashba spin–orbit interaction. The spin precession is complete isoamplitude for normal incidence. For inclined incidence, the precession disappears when the effective exchange field is set into a certain range. It is also found periodical electrostatic field can revive the disappeared precession, but electronic transport is suppressed, which leads to some dips in the conductance spectrum.
