The wiping-out property of the moving model (magnetic hysteresis)

摘要

Some properties of the moving Preisach model are examined. It is found that this model can introduce hysteresis in materials where it is not intrinsically present. It is shown that the moving model has the wiping-out property, even in the case where a reversible component of magnetization is present in addition to the irreversible component computed by the moving model. The implication of this model to the overwrite problem in magnetic recording is discussed.
