Influence of grain boundaries on orientation of spontaneous magnetization inside domains in the Fe-3 % Si ferromagnetic sheets

摘要

Some peculiarities of the spatial distribution of magnetization (M) over right arrow (S) inside stripe domains near the planar grain boundaries in the sheets of soft magnetic alloys such as Fe-3%Si with orientation (011) m demagnetized state are investigated. By means of solution of the Landau-Lifshitz equation, the equilibrium magnetization configurations are calculated and mechanisms of their formation are discussed. An existence of 180degrees domain walls bending under the action of the magnetostatic fields at the grain boundary was theoretically grounded. [References: 8]
