Abstract
Magnetization processes in melt spun and sintered Nd-Fe-B-permanent magnets are significantly different because of their distinct grain size. We deduce from magnetization measurements on randomly oriented material that in melt spun Nd-Fe-B the homogeneous rotation of magnetization plays an important role in the whole field range, while for sintered magnets after thermal demagnetization an easy domain wall movement is the predominant process.
