We study the spin-sensitive scattering of the spin-orbit (SO) coupled cold atom subject to a moving spin-independent rectangular potential barrier. Due to that SO coupling breaks Galilean invariance, the spin orientation of the atom can be switched unidirectionally and thus can serve as a one-way sp...
