We report exact model calculations of the spin-dependent tunneling in doublemagnetic tunnel junctions in the presence of impurities in the well. We showthat the impurity can tune selectively the spin channels giving rise to a widevariety of interesting and novel transport phenomena. The tunnelingmagnetoresistance, the spin polarization and the local current can bedramatically enhanced or suppressed by impurities. The underlying mechanism isthe impurity-induced shift of the quantum well states (QWS) which depends onthe impurity potential, impurity position and the symmetry of the QWS.Comment: 4 pages, 4 figures, submitted to Phys. Rev. Let
