Beschreibungen/Notizen

• Arrays of circular and eliptical antidots with interhole distances much larger than hole dimensions have been fabricated by electron beam lithography and plasma etching on amorphous magnetic films with a well defined uniaxial anisotropy. In this diluted regime, each hole can be considered as an isolated inclusion in the homogeneous film. The effect of patterning is a moderate increase in coercivity while the overall magnetic anisotropy is dominated by that of the original film with an additional contribution due to the shape anisotropy of the artificial array.
