摘要：

We report on structural and magnetic studies of diode rf-sputtered fcc Cu/Co (100) multilayers. All samples exhibit a nearly monocrystalline periodic structure with roughness of about 6 angstrom. We observe oscillations of magnetoresistance as the Cu layer thickness is varied. The maximum of magnetoresistance is found for t(Cu) = 18.5 angstrom (up to DELTA-R/R congruent-to 6%), and a differential magnetoresistance as high as DELTA-R/R DELTA-H congruent-to 1.4 kOe-1 is obtained. An appropriate combination of antiferromagnetic coupling and quadratic in-plane anisotropy is responsible of this enhancement.
