Oscillations of magnetoresistance and thermoelectric power vs. both nonmagnetic spacer and ferromagnetic slab thicknesses are studied in the current-perpendicular-to-plane geometry, in terms of the single-band tight-binding model. The spin-dependent conductance was calculated from the Kubo formula by means of a recursion Green function technique, and the thermoelectric power directly from the well-known Onsager relations. In general, the observed oscillations may have either just one or two periods. In the latter case the long period of oscillations, related to spectacular beats, is apparently of non-RKKY type. The relative thermoelectric power oscillations are strongly enhanced in comparison with those of the giant magnetoresistance, have the same periods, but different phases and a negative bias.
