We study ballistic electron transport through single or double barriers on monolayer MoS2, of width d, in the presence of a ferromagnetic field Moran antiferromagnetic field F. The total conductance,gc, its spin-up and spin-down components, and the polarization oscillate with d or the distance b between two barriers. The corresponding oscillation periods are different. The conductance g(c) versus M decreases in a fluctuating manner with a steep decline at certain value of M. As a function of M the spin polarization P-s oscillates before it becomes 100% while the valley polarization 13, oscillates and steadily increases.
