a Time t dependent carrier density Δn. The frequency of pump and probe beams employed in the simulation was set to the equivalent value of our experimental condition (3.5 THz). b Three-dimensional magnetic field B distribution near graphene disk at t = 0. The strength of the magnetic field of the surface of graphene disk is illustrated by color code.
