Abstract
We demonstrate that periodic magnetic nanostructures can be fabricated by depositing perpendicular magnetic films on self-assembled surfaces by ion beam bombardment. Similar stripe domain patterns and reduced coercivity are observed for the as-deposited sample as compared with those for a reference sample with unbombarded substrate. Further processing steps such as etching and polishing will be needed to isolate the magnetic elements from each other, in order to make ultrahigh density magnetic storage media.
