Abstract

The remanence enhancement, phase fractions, and coercivity mechanism of Nd2Fe14B/α-Fe and Nd2Fe14B/Fe3B nanocomposite magnets were studied using the micromagnetic theory. It was found that magnetocrystalline anisotropy energy density K, together with saturation magnetization Ms of the soft magnetic phase, plays a key role in the actual value of coercive fields for both Nd2Fe14B/α-Fe and Nd2Fe14B/Fe3B nanocomposite magnets. The differences between magnetic properties of Nd2Fe14B/α-Fe and Nd2Fe14B/Fe3B were successfully explained. Theoretical results support the experimental values.
