In this study, alpha -Fe/Nd2Fe14B nanocomposite magnets with strong crystal
lographic texture were prepared by controlled melt spinning. For a relative
ly low wheel speed of 10 m/s, the c-axis texture of the Nd2Fe14B crystals i
s predominantly perpendicular to the plane of the ribbon, but it switches t
o 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 ribb
on planes. High remanence of 0.74M(s) and a large energy product of 24.3 MG
Oe were observed parallel to the ribbon plane direction in the magnets prep
ared at a wheel speed of 20 m/s. (C) 2001 American Institute of Physics.
