N2 - The spin-dependent conductance and magnetoresistance (MR) in ferromagnetic double junctions are studied theoretically, taking into account discrete energy levels and a finite spin relaxation time. The basic results are applied to hybrid tunnel junctions, in which nano-scale grains are embedded in the tunnel barrier. With increasing size quantization and spin relaxation time the MR is found to be enhanced at low temperatures.
