Query: Effects of Fermi velocity engineering in magnetic graphene superlattices   In this work we investigate theoretically the influence of a Fermi velocity
modulation in the electronic and transport properties of magnetic graphene
superlattices. We solve the effective Dirac equation for graphene with a
position dependent vector potential and Fermi velocity and use the transfer
matrix method to obtain the transmission coefficient for the finite cases and
the dispersion relation for a periodic superlattice. Our results reveals that
the Fermi velocity modulation can control the resonance peaks of the
transmittance and also works as a switch, turning on/off the transmission
through the magnetic barriers. The results obtained here can be used for the
fabrication of graphene-based electronic devices.
