Abstract
Coercivity is the essential property characterizing hard magnetic materials, in particular with respect to normal ferromagnets. It exists when low field domain wall motion does not take place, either the magnetization being already saturated in zero field, or domain walls being pinned at structural heterogeneities. In these two cases, the magnetic configuration of the system is an energy minimum in the field, although it may not be the lowest energy minimum. This energy minimum vanishes at H = He, the coercive field. Then magnetization reversal takes place and the system reaches the lowest energy state.
