Abstract :
Sintered Nd-Fe-B based permanent magnets where either the Nd was partly substituted by Dy or the Fe by Co or both (Dy and Co) Were studied with respect to their anisotropy field HAand their hysteresis loop between 100K and the Curie temperature. Dy increases HAand consequently the coercivityxHc. Co reduces HAonly slightly, howeverxHcdecreases strongly. Substituting Dy and Co delivers a magnet with a temperature behaviour comparabel to a pure Nd-Fe-B magnet.
