抄録: | This study presents an efficient representation of macroscopic magnetization process based on the bifurcation property of mesoscopic two-domain magnetic particles. The macroscopic magnetization model, called the assembled domain structure model (ADSM), is constructed by assembling mesoscopic particles. Bifurcation is discussed of the two-domain state from the single-domain state in the unit mesoscopic particle in the ADSM. Based on this state bifurcation, a procedure to switch the macroscopic magnetization-state transition in the ADSM is developed, which dramatically reduces computation times in macroscopic magnetization simulations. |
