The Jiles-Atherton model of magnetic hysteresis was introduced in 1984. This is one of the most popular models of magnetic hysteresis. Its main advantage is the fact that this model enables connection with physical parameters of the magnetic material. Jiles-Atherton model enables calculation of minor and major hysteresis loops.〔 The original Jiles-Atherton model is suitable only for isotropic materials.〔 However, an extension of this model presented by Ramesh et al. and corrected by Szewczyk enables the modeling of anisotropic magnetic materials. == Principles == Magnetization of the magnetic material sample in Jiles-Atherton model is calculated in the following steps 〔 for each value of the magnetizing field : * effective magnetic field is calculated considering interdomain coupling and magnetization , * anhysteretic magnetization is calculated for effective magnetic field , * magnetization of the sample is calculated by solving ordinary differential equation taking into account sign of derivative of magnetizing field (which is the source of hysteresis). 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「Jiles-Atherton model」の詳細全文を読む スポンサード リンク
