Abstract

The patterning of magnetic antidot-type array by Ga⁺ implantation was discussed. It was found that the hard axis bit-like domains arised at remanence when the demagnetising energy, determined by the number and spatial distribution of free poles on the antidot edges, and the uniaxial anisotropy of the film were of same order. The analysis suggested the consideration of an additional energy density term accounting for the pinning of domain walls at implanted regions while studying the domain structure in these systems.
