Abstract
The remanence enhancement, phase fractions, and coercivity mechanism of Nd2 Fe14B/alpha-Fe and Nd2Fe14B/Fe3B nanocomposite magnets were studied using t he micromagnetic theory. It was found that magnetocrystalline anisotropy en ergy density K, together with saturation magnetization M-s of the soft magn etic phase, plays a key role in the actual value of coercive fields for bot h Nd2Fe14B/alpha-Fe and Nd2Fe14B/Fe3B nanocomposite magnets. The difference s between magnetic properties of Nd2Fe14B/alpha-Fe and Nd2Fe14B/Fe3B were s uccessfully explained. Theoretical results support the experimental values. (C) 1999 Elsevier Science Ltd.
