- 論文の詳細を見る
In this paper, the magnetization processes in cubic particles from initial saturation states are calculated by numerical micromagnetics. For particle sizes small than 800Å, the remanent state has flowerlike magnetization configuration. Beyond 800Å this state is replaced by a vortex structure. The angular dependence of the coercivity field is calculated for particle sizes of 400Å, 600Å, 700Å, 750Å, 800Å, and 900Å. For particle sizes small than 700Å, they switch mostly in the coherent rotation. For particle sizes between 700Å and 800Å, the magnetization reversal process changes from coherent rotation to incoherent fanning. Beyond 800Å, the magnetization reversal process is probably due to the wall motion.
