摘要：

This paper presents a linearized demagnetization model taking into account temperature dependence of the hard magnetic material. At the same time, an efficient searching algorithm is proposed to properly identify the new worst working point and update the recoil line during the entire transient solution process if a working point is discovered below the knee point of the current recoil line. This model is further extended to take into account the temperature dependence of irreversible demagnetization behaviors.
