摘要：

The magnetic properties of iron particles aggregates of different packing density p are analysed. In some cases, when p increases, the coercive field has an initial increase followed, after a distinct maximum, by a decrease. This behavior is ascribed to the formation of chains of particles whose effect is opposite to the effect due to the formation Of Clusters. The chain formation increases the maximum anisotropy field because of the increase of the shape anisotropy. From the rotational loss measurements it is shown that fanning is the magnetization reversal model.
