Abstract :
The authors report electron microscopic studies of domain wall pinning at grain boundaries in Fe77Nd15B8 sintered magnets. A wall was observed to be strongly pinned at a triple junction of grain boundaries, in what was determined to be ferromagnetic bcc phase material. This agrees with Hiraga et al´s suggestion that bcc phase boundary regions are closely related to the magnetic properties of the material.
