Reversibility of the Preisarch Model

摘要

The classical Preisarch model normally computes the irreversible component of the magnetization dur to the limit of zero initial slopes of reversal curve. However, it is necessary to model the reversible component of the magnetization in order to obtain accurate description of the magnetization. The paper describpts methods of dealing with the reversible component in the scalar Presisach model (Mayergoyz's non-linear Presisach model and E.Della Torre's moving model and product model), we propose a extened vector Presiach model take into account the reversible component of magnetization based on Mayergoyz's vector model.
