Abstract (in Japanese) (See Japanese page) 
(in English) Magnetoimpedance (MI) sensors with ultrahigh sensitivity have been studied for application to wearable computers and medical devices . To realize these applications, it is of prime importance to analyze dynamic magnetization process in amorphous wires. In this paper, we introduce micromagnetic analysis of dynamic magnetization process in an amorphous wire by using the Landau-Lifshitz-Gilbert (LLG) equation taking into account the eddy current field derived from Maxwell’s equations. The simulation results are in good agreement with the experimental results.
