Abstract
This paper presents the changes that appear in the properties of particulate magnetic media for high packing fractions and good orientations of the easy axes of the particles. In particular, the forming of clusters in strongly correlated media will lead to a degeneration of the interaction field distribution and, consequently, of the Preisach distribution. The effects are not observed when reducing the packing fraction or for random oriented easy axes of the particles.
