摘要：
We report on structural and magnetic properties of diode rf-sputtered fcc Cu/Co(100) multilayers. All the samples exhibit a pseudo-epitaxial structure with interface roughness of the order of 6 angstrom. As the Cu layer thickness is varied, we observe oscillations of magnetoresistance corresponding to oscillations of the interlayer coupling. The maximum of magnetoresistance is found for t(Cu)=18.5 angstrom (up to DELTAR/R almost-equal-to 6%). We furthermore measure a very high differential magnetoresistance (DELTAR/RDELTAH=1.4 kOe-1). A combination of antiferromagnetic coupling and quadratic in-plane anisotropy is responsible for this large value of magnetoresistivity.
