▎ 摘 要
In this work we investigate theoretically the transport properties of a magnetic graphene superlattice in the presence of a modulation of the Fermi velocity solving the effective Dirac equation. Using the transfer matrix method, we obtain the transmission coefficient of the system. We find that the transport properties are very sensitive to the modulation of the Fermi velocity, being possible, for instance, to obtain different behaviours for the system, such as an incidence angle-dependent miniband and minigap structure or a suppression of the transmission. We also obtain that it is possible to create a magnetic filter that can be controlled by the Fermi velocity. The results obtained her e can be used for the fabrication of graphene-based electronic devices.
