Rare earth–cobalt hard magnetic nanoparticles and

Mar 30, 2010High-energy ball milling has been shown to be a promising method for large-scale fabrication of rare earth–transition metal nanoparticles. In this work, we report crystallographically anisotropic SmCo 5, PrCo 5 and Sm 2 (Co, Fe) 17 nanoparticles (particle size smaller than 10 nm) obtained by surfactant-assisted ball milling and study their size and properties as a function of the milling
