Micromagnetic study of Nd 2Fe 14B/α-Fe and Nd 2Fe 14B/Fe 3B nanocomposite magnets
Abstract
The remanence enhancement, phase fractions, and coercivity mechanism of Nd 2Fe 14B/α-Fe and Nd 2Fe 14B/Fe 3B 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 Nd 2Fe 14B/α-Fe and Nd 2Fe 14B/Fe 3B nanocomposite magnets. The differences between magnetic properties of Nd 2Fe 14B/α-Fe and Nd 2Fe 14B/Fe 3B were successfully explained. Theoretical results support the experimental values.
