  • Abstract
    Various contributions to the magnetic anisotropy energy (MAE) dispersion for an assembly of CoPt nanoparticles are examined, using the empirical Neel anisotropy model. It is shown that, while small shape and composition variations have negligible effects, the statistical distribution of chemical arrangements can be the major source of MAE dispersion.
