要約(英語): Recently, core loss evaluation and magnetization process analysis at high-frequency have become more important. Fiorillo et al. proposed the method to analyze the frequency characteristic in magnetization process by separating into reversible and irreversible processes. However, it is necessary that the complex convergence calculation and the core loss measurements to low-frequency for analysis. Therefore, the procedure is complicated and it is difficult to apply the method to the materials which are difficult for measuring the core loss to low-frequency. In order to solve the issue, we have examined the simpler method which is separating the magnetization process into reversible and irreversible.
