摘要：
The magnetic domain structure of R-Fe-B alloys has been examined in several alloys from the less anisotropic Y-Fe-B to the most anisotropic Tb-Fe-B. In samples with larger grains the domain walls are observed to be pinned at grain boundaries. When the size of the grains is very fine, some very large domains are observed to coexist together with the much finer single domains. These large interaction domains are formed because of strong interactions between spins of adjacent domains.
