| Zusammenfassung: | Anisotropic magnets based on Nd(Fe,Mo)12Nx nitrides were prepared by a milling process. Particle size dependence of the coercivity has been investigated. The optimizing size which accompanies the highest coercive force was examined by transmission electron microscopy. A coercive force iHc of up to 6.2 kOe, and a maximum energy product (BH)max of up to 12.0 MG Oe were obtained. The mechanism of the coercivities is discussed with a comparison of the powders prepared by mechanical alloying. The variation of coercive force as a function of temperature is reported. |
