Structure, Composition and Magnetic Properties of Nd-(Fe,Co)-B Hard Magnetic Copper-Doped Powders

Hard magnetic Nd-(Fe,Co)-B powders prepared by ball milling from melt-spun ribbons are investigated. The effect of doping by 1 wt% Cu on magnetic properties is shown. Furthermore, the thermal stability of the Nd-(Fe,Co)-B powder with Cu doping is studied. The structure and morphology of the powders...

Zusammenfassung:	Hard magnetic Nd-(Fe,Co)-B powders prepared by ball milling from melt-spun ribbons are investigated. The effect of doping by 1 wt% Cu on magnetic properties is shown. Furthermore, the thermal stability of the Nd-(Fe,Co)-B powder with Cu doping is studied. The structure and morphology of the powders are observed. The contribution of the Nd 2 (Fe, Co) 14 B and α-(Fe,Co) phases to the magnetic properties is determined using the temperature dependences of AC susceptibility in the range of 17 to 847 °C. The reversal magnetization and energy product of the Nd-(Fe,Co)-B powders with and without Cu doping are investigated and discussed.
