The effect of spin-involved interaction on the transport properties of disordered two-dimensional electron systems with ferromagnetic contacts is described using a two-component model. Components representing spin-up and spin-down states are supposed to be coupled at a discrete set of points. We have found that due to the additional interference arising in two component systems the difference between conductances fur the parallel and antiparallel orientations of the contact magnetization changes its sign as a function of the length of the conducting channel.
