Abstract
We have carried out measurements of the magnetic-field dependence of the ma gnetoresistance [MR(H)] in the current perpendicular to the plane (CPP) mod e for magnetic multilayers having the following configurations: [Fe/Cu/Co/C u](N) and [Fe/Cu](N)[Co/Cu](N). The two configurations had the same number, types, and thicknesses of magnetic and nonmagnetic layers; their only diff erence lay in the ordering of the magnetic layers. Nevertheless, the measur ed MR(H) curves are found to be completely different for the two configurat ions. The implications of these results are discussed for the spin-diffusio n length.
