We present an extensive numerical study of the ballistic current perpendicular to the plane (CPP) GMR. Using an original technique to calculate the spin conductance in the ballistic regime we studied A/B superlattices attached to pure crystalline semi-infinite leads, with A either Ni or Co, and B various 3d, 4d and 5d transition metals, with an FCC structure. From this analysis the Co/Ag and Co/Cu systems possess the larger GMR ratios, and this is mainly due to (i) a large off-set between the Cu (Ag) band and the minority spin sub-band of Co, and (ii) strong interband scattering at the interfaces in the minority spin sub-band.
