Abstract
In this study, α-Fe/Nd2Fe14B nanocomposite magnets with strong crystallographic texture were prepared by controlled melt spinning. For a relatively low wheel speed of 10 m/s, the c-axis texture of the Nd2Fe14B crystals is predominantly perpendicular to the plane of the ribbon, but it switches to parallel to the ribbon plane direction at a higher wheel speed of 20 m/s. The magnets show strong magnetic anisotropy between in and out of the ribbon planes. High remanence of 0.74Ms and a large energy product of 24.3 MGOe were observed parallel to the ribbon plane direction in the magnets prepared at a wheel speed of 20 m/s.
