摘要：

In this paper we report on the effects of particle interactions in fine Barium ferrite particles suitable for use as recording media. We also report on measurements of activation volumes of reversal. From measurements of different pigments, the activation volumes are found to be comparable to the physical size of the particles. However particle interactions are found to increase the value of the activation volume.
