Abstract
Au/Co artificial superstructure films were prepared by an alternating deposition technique in ultra-high vacuum. A large perpendicular anisotropy was found to occur when the Co layers were thinner than 20 Ã
. From torque measurements the maximum value of K¿ at room temperature was estimated to be 9.6 à 106 erg/cm3. The surface anisotropy energy constant Ks was about 0.4 erg/cm2. The magnetoresistivity was measured as a function of a perpendicular applied magnetic field. The magnetoresistivity curve obtained was hysteretic, showing a peak in the vicinity of Hc . The maximum change in resistivity was about 4% at 77 K.
