Controllable valley and spin-polarized transport and negative magnetoresistance in a silicene junction

We investigate the valley and spin-resolved transport through a ferromagnetic/ferromagnetic/ferromagnetic silicene junction. For the normal silicene junction with zero exchange field in the presence of photo-irradiation, we observe a 100% valley/spin polarization by modulating the energy E. By enhan...
