Abstract

Several Co / Ru multilayers were grown in which the magnetization directions of consecutive Co layers were aligned antiparallel and along the film normal. The magnetization curves for these multilayers agree with the curves obtained by minimizing the total energy including anisotropy and interlayer coupling. These multilayers were part of a series with Co thicknesses of 11 and 22 Å and Ru thicknesses varying between 5 and 20 Å. Torque and magnetization measurements showed that the multilayers with 11 Å Co had a perpendicular easy axis while for the 22 Å Co series an in-plane preferential orientation was observed. A strong antiferromagnetic interlayer coupling was obtained for Ru thicknesses of about 8 Å.
