Popis:	Soft magnetic alloys Fe95Nd5and Fe89.5Nd10.5were made by the mechanically ball milling to investigate the influence of Nd doping on the magnetic properties of Nd2Fe14B/α-Fe nanocomposite magnets. The coercivity was enhanced with increasing Nd of the pre-alloyed Nd-Fe soft powders. The further discussions on Nd2Fe14B/α-Fe nanocomposite were also carried out through directly mixing the pure Nd as the interface improving agent. Compared with Nd-Fe pre-alloys, the direct addition of Nd was more favorable to reinforce the coercivity of nanocomposite magnets and the squareness of demagnetization curve, thereby increasing the maximum magnetic energy product.
