title = "Magnetic and microstructural characteristics of Nd-Fe-B sintered magnets produced by Dy sputter coating process",
abstract = "High-coercivity magnets were fabricated via a sputter coating process. A powder was successfully made in core-shell type structures by coating Nd-Fe-B powder with dysprosium nanoparticles. The maximum thickness of the Dy shell was 69.5 nm. The sputter coating of the Nd-Fe-B powder yielded samples with densities greater than 98\% as a result of the effective penetration of (Nd,Dy)2Fe14B phases in the hollows between neighboring Nd2Fe14B grains. The microstructures of the (Nd,Dy)2Fe14B phases were effectively controlled, resulting in improved magnetic properties. Thus, the maximum coercivity of the samples increased from 934.8 to 1072.8 kA/m after the Dy sputter coating process.",
