    Anisotropic PrCo Nanoparticles by SurfactantAssisted Ball

    Magnetically hard PrCo sub 5 sub nanoparticles have been produced by using surfactant-assisted high-energy ball milling techniques. The use of surfactant leads to the dispersion of the crashed particles and prevents them from rewelding during the milling process. Heptane was used as the milling medium, and oleic acid as the surfactant.
