ABSTRACT
Using polarized neutrons, we measured grazing-incidence scattering from a mesoscopic permalloy antidot array. A kinematical theory incorporating a highly anisotropic resolution function was developed to interpret the data. Calculations for a magnetic domain structure of the antidot array were obtained from a micromagnetic simulation and show good agreement with the experiment. In contrast, calculations based on a model of uniform magnetization between the antidots were not found to be consistent with the data.
