초록

Magnetic 0-D Nd2Fe14B powders are successfully fabricated using 1-D Nd2Fe14B nanowire formed by an efficient and facile electrospinning process approach. The synthesized Nd-Fe-B fibers and powders are investigated for their microstructural, crystallographic, and magnetic properties according to a series of subsequent heat treatments. Each heat-treatment process leads to the removal of organic impurities and the formation of the respective oxides/composites of Nd, Fe, and B, resulting in the formation of Nd2Fe14B powders. Nd-Fe-B fibers exhibit the following magnetic properties: The coercivity (Hci) of 3260 Oe, a maximum magnetization at 3T of 109.44 emu/g, and a magnetization remanence (Mr) of 44.11 emu/g. This process easily mass produces hard magnetic Nd2Fe14B powders using a 1-D synthesis process and can be extended to the experimental design of other magnetic materials.
