Abstract :
Full characterization of particulate recording media requires the modeling of both the reversible and the irreversible components of the magnetization. Experiments show that the height of minor loops originating from negative saturation is not an even function of the magnetization. A moving Preisach-type model with reversible magnetization that is capable of calculating these results is introduced. The properties of the model are discussed. It is shown that previous models are special cases of this model
