ECC媒体における磁気クラスタサイズの磁場印加方向依存性

抄録

  The effect of applied magnetic field direction on the magnetic cluster size of exchange coupled composite (ECC) media was analyzed by using micromagnetic simulation. The magnetization distribution in all cases exhibited a maze domain structure. The magnetic cluster size decreased as the applied field direction tilted from perpendicular to in-plane. For the hard layer only and the soft layer only, the magnetic cluster size in the perpendicular applied field was the same as that in the in-plane field. The soft layer dominated the magnetic cluster size of the ECC medium in the perpendicular field, whereas the hard layer dominated that in the in-plane field.
