Magnetization direction in the micromagnetic knot of the defect and study of its characteristics
The Micro-magnetic fixed knot which dont depend on the outer magnetic field formed near the defects, because the domain wall in the ferro-magnets is pinned by the defect. In this paper, the distribution of the magnetization field in the micro-magnetic fixed knot is computed according to the change of the energy based on the method of minimum energy. We can inspect and distinguish the defect from the character of distribution of the magnetization field, then provide the base of the magnetic theory for realizing micro-magnetic testing from the point of the mechanism of the micro-magnetic.
