We study the spin-dependent magneto conductance in mesoscopic rings subject to an inhomogeneous in- plane magnetic field. We show that the polarization direction of transmitted spin- polarized electrons can be controlled via an additional magnetic flux such that spin flips are induced at half a flux quantum. This quantum interference effect is independent of the strength of the nonuniform ...
