As demonstrated here on CoPt nanoparticles, flash laser annealing

• laser irradiation. This technique is then very interesting for magnetic alloy nanoparticles studies and applications because it opens up a new way to fabricate size-controlled spherical nanoparticles with narrow size dispersion. Keywords: magnetic alloy nanoparticles; nanoparticle morphology
