We report on the magnetic properties and anisotropic magnetoresistance behavior of engineered bicomponent array of “holes” with alternating diameters embedded in a continuous permalloy film. We observed that the magnetization reversal is significantly altered when compared to a homogeneous array of antidots, and exhibits strong dependence on the permalloy thickness. Our results demonstrate that the use of two antidot sublattices greatly enhances the parameters available for engineering the…
