通过观察具有诱导各向异性易轴的磁畴，研究了非晶带在磁化硬轴上的磁化过程。研究发现，施加在纵向上的磁场通过重新排列静磁能和壁面能之间的能量平衡，引起壁面运动和磁化旋转。在没有磁场的情况下，将带在残余状态下再退火，引起畴壁钉住，抑制了畴壁运动，显著改善了高频磁性能。
Magnetization process of amorphous ribbons in the hard axis of magnetization was investigated by observation of magnetic domains having the easy axis of induced anisotropy in the transverse direction. It was found that a field applied in the longitudinal direction caused wall motion as well as magnetization rotation through re-arrangement of energy balance between magnetostatic and wall energies. Re-annealing of ribbons in a remanent state without a magnetic field caused domain wall pinning that restrained wall motion and improved the magnetic properties at high frequency markedly.
