Abstract

Self-assembled arrays of nanospheres have been used to pattern a CoPt multilayer into nanopillars. On top of this has been deposited a CoRu multilayer, which is antiferromagnetically coupled. The nanopillars introduce a known structural and magnetic lateral modulation into the multilayer. Soft x-ray magnetic scattering was used to observe the interference patterned from the patterned substrate. This has allowed us to show how the magnetic roughness correlates with the structural roughness and obtain selective magnetometry of the various magnetic elements.
