Abstract
The angular dependence of the nucleation field H-n in high-coercivity grains of sintered Nd-Fe-B and SmCo5 magnets has been studied by direc t observations of the domain structure in an external magnetic field. The effect of the stray field of surrounding grains on the angular dep endence of H-n has been estimated quantitatively. It is found that cha nges in H-n of individual grains as large as 0.45 T may be observed, d epending on the micromagnetic state of neighbouring grains.
