- 論文の詳細を見る
The single domain size of ferromagnetic cubic particles are invesgated by micromagntics simulation. The angular dependence of coercive forces and the angular dependence of hysteresis loops for particles of sizes 250Å, 350Å, 450Å, 500Å, 520Å, 530Å and 550Å are calculated and discussed. For a particle of size smaller than 450Å, it switches mostly in the coherent rotation, for a particle of size 500Å, its magnetization reversal resembles the incoherent fanning, while for a particle of size larger than 520Å, its magnetization reversal is due to the wall motion. The single domain size for cubic particle is about 510Å.
