We investigate spin transport through magnetic potential structures in single graphene layer with the consideration of Zeeman effect. We find that the magnetic step leads to the spin-dependent transport, and the spin-polarized conductance has the oscillatory behavior as a function of fermion energy. Furthermore, the electrostatic delta-potential added to the magnetic step causes dramatic changes in the spin transport. The spin polarization can be reversed by the application of the electrostatic delta potential, leading to so called spin-switching effect. We expect that the spin-switching effect in this study gives rise to great convenience for experimental investigations on graphene spintronics.
