Query: Controllable valley and spin transports in ferromagnetic silicene
  junctions   We investigate charge, valley, and spin transports in
normal/ferromagnetic/normal silicene junc- tion. We show that the charge,
valley, and spin conductances in this junction oscillate with the length of the
ferromagnetic silicene. It is also found that the current through this junction
is valley and spin polarized due to the coupling between valley and spin
degrees of freedom, and the valley and spin polarizations can be tuned by local
application of a gate voltage. In particular, we find fully valley and spin
polarized current by applying the electric field. We also obtain the condition
for observing the fully valley and spin polarized current.
