Abstract

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
