▎ 摘　　要

Graphene has a long spin relaxation length due to its weak intrinsic spin-orbit effect and potentially is attractive for spintronics. Here, the effect of the different applied gate and bias voltages on the time-dependent spin and charge tunneling currents in a system including a magnetic molecule located on a graphene layer with ferromagnetic leads is investigated. We show that the system under investigation could be regulated by applying gate voltage and a time-dependent bias voltage. We also show that the interaction between graphene and magnetic molecule has the principal effect on the electron and spin transport in the system.
