In this paper, a moving Preisach-type model with reversible magnetization is introduced to calculate the height of minor loops originating from negative saturation in a particulate recording media.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. >read more

TL;DR: In this paper, an efficient numerical technique for the implementation of Preisach-derived models is presented, where it is shown that, when efficiently implemented, all preisach derived models require only a few table lookups at each field value to compute the magnetization for both locally reversible and irreversible components.

Mathematical models of hysteresis
TL;DR: A new approach to the scalar Preisach model of hysteresis, which emphasizes its phenomenological nature and mathematical generality, is described in this paper, which gives the necessary and sufficient conditions for the representation of actual hystresis nonlinearities by the scalareach model.
