Abstract :
In this paper, we report investigations on circular magnetic domain structure in amorphous microwires. Polar magneto-optical Kerr microscopy was used for the observation of the magnetic domains images. The surface magnetization reversal is determined basically by the circular domains nucleation. For the first time, the rearrangement of the surface domain structure is observed as a part of the magnetization reversal process in amorphous microwires.
