Abstract:
This paper introduces the surfactant-assisted ball milling which was used to prepare the rare earth permanent magnet nanomaterial. We prepared the nanoparticles、permanent nanoflakes and nanostructured bulks. The rare earth permanent magnet nanomaterial played an important role in different application areas. The effect of milling time and different surfactants on the microstructure、morphology and magnetic properties were studied using the XRD、 FESEM and VSM. It shows that the surfactant played an important role in the milling process. The change of surfactant and the process conditions have an important role in controlling the morphology and magnetic properties of the powders. Finally, there were some the problems of the SABM in recent researches, it deserves further research.
