The magnetic and transport properties of multilayer antidot nanostructure have been systematically
investigated. The structures consisting of Co 30 nm /Cu tCu nm /Ni80Fe20 30 nm were
fabricated using deep ultraviolet lithography followed by lift-off process. We observed that the
magnetization reversal processes are markedly dependent on tCu due to the interplay of different
interlayer coupling mechanisms. The transport properties of the antidot arrays typically show a
superposition of anisotropic and giant magnetoresistance effects, and the relative magnitude of the
two effects is strongly sensitive to tCu. This is completely different from the observations in the
corresponding continuous films. 2006 American Institute of Physics. DOI: 10.1063/1.2208276
Advances in nanofabrication techniques have stimulated
interest in the patterned magnetic mesostructures. Recently,
antidot structures, formed by arrays of holes embedded into
contiguous magnetic film, have attracted a lot of attention.19
