摘要：

A Preisach-Arrhenius aftereffect model, that accurately calculates the entire relaxation process, including the linear log-time region, is used to describe some other characteristics of the time decay. The location of the peak of the decay coefficient is shown to be less than the peak of the irreversible coercivity by an amount that is a function of the standard deviation of the critical field, the fluctuating field, and the moving parameter. The model computes a magnetization decay that includes nonmonotonic behavior under certain circumstances, depending upon the applied field history. A conclusion of this paper is that procedures for accelerated testing of magnetic media are suspect.
