For fine α-Fe. particles, prepared from acicular α-FeOOH. particles industrially, intergrain Necking-Configurations [:NC's] were crystallographically characterized and their effects on particle-magnetizations were numerically studied by simplified morphological-model, which was based on a concept of "interaction-anisotropy" developped by Jacobs and Bean and known as "Chain-of-Spheres" Fanning-Model [:CSFM]. It is shown that "symmetric-fanning" mechanism is most important for almost all the NC's, but "non-symmetric" type becomes dominant in the "multi-domain" like NC's, where strong repulsive dipole-dipole interactions arise, and for angular dependence of coercive force, comparisons with experiments for the particles with the typical NC's are also discussed.
