The aim of this work was the fabrication of Nd2Fe14B nanoparticles, through a topdown technique like surfactantassisted highenergy ballmilling, and the monitoring of the millingprocess stages with respect to the structure and magnetism. The
The high coercivity of 26.2 kOe for SmCo 5 nanoflakes are obtained by multistep three steps surfactantassisted ball milling. The magnetic properties, phase structure and morphology are studied by VSM, XRD and SEM, respectively. The results demonstrate that the three step ballmilling can keep more complete crystallinity relatively less defects during the process of milling compared with

Surfactantassisted high energy ball milling HEBM is a widely used technique for producing nanostructured magnetic materials with oleic acid OA being the most commonly utilized surfactant reported in literature to date. No conclusive explanation has been presented for the wide use of OA and only a few studies have deviated from its use.
An ingot of NdFeB alloy was disintegrated by hydrogen decrepitation HD. Highenergy ball milling technique with hard metal milling elements and balls was employed to refine HD powders down to particle size optimum for magnet processing.
