ANISOTROPY IN Nd_(12)Fe_(77)Co_5B_6 MELT  SPUN FLAKES

Abstract

Abstract: Alloyof composition Nd12 Fe77 Co5 B6 was melt spun into flakes and then annealed. The magnetic propertiesandthe microstructureoftheflakesand powders were analyzed via VSMdemagnetization curves and XRDpatterns. New phenomenon that anisotropy existsin an nealed flakes wasfounded. Theorientationofthetextureparallelstothec axisthatistheeasy magnetization axisof Nd Fe B typecrystal.Itisveryusefulfor manufacturing high perfor mancebonded magnets with good magneticandtemperature properties.

Key words: Nd Fe B, magnet, anisotropy, melt spin , anneal
