We developed a new technique using self-organization of binder that enabled the alignment of a molecular chain. By using this technique, we controlled the flexibility of Nd-Fe-B-based rigid sheet magnets, transformed them into various shapes, and succeeded in preparing radially anisotropic ringor arc-shaped magnets. Optimizations of the consolidation process of the self-organization binder under a transverse alignment field and the transformation process into various specific shapes realized radially anisotropic magnets with 160 kJ/m 3 in (BH)max.
