In this work, we study the magneto-optical properties of monolayer silicene under a perpendicular magnetic field. We calculate the linear, third-order nonlinear, and total absorption coefficients and relative refractive index changes as functions of the photon energy and the magnetic field. The magneto-optical absorption coefficients and relative refractive index changes appear in two different regimes: the THz and the visible frequency. Our results showed that the resonant peaks are blue-shifted with the magnetic field. The results demonstrate the potential of monolayer silicene as a new two-dimensional material for applications in optical devices as a promising alternative to graphene.
