Measuring the L10 chemical order parameter of a single CoPt nanoparticle smaller than 4 nm

Résumé

We discuss the possibility of L10 chemical order parameter quantification for an individual particle of CoPt, using transmission electron microscopy. While "usual" approaches are found to be unapplicable for small particles (less than 4 nm in diameter), we present a method based on the comparison between an experimental high-resolution image and simulated ones with various degrees of chemical order. © 2011 American Physical Society.
