Аннотация: In the present study, the domain structure of high-coercivity and high-performance Nd–Fe–Bbasedpermanent magnets, which were prepared by the binary mixture blending technology in using rareearthmetal hydrides, is studied by atomic force microscopy. The domain structure is observed both perpendicularand parallel to the magnet texture axis; these surfaces are shown to be characterized by maze-likedomain structure with spike domains and strip domains, respectively. The domain structure is analyzed with3D images. Substantial changes in the domain structure of Nd–Fe–B magnet prepared with DyHx hydrideaddition are demonstrated and analyzed; the formation of single-domain grains is demonstrated. The domainstructure of Ce-containing magnets with the high coercive force is studied.
