摘要: We have enlarged the theory of coercive force to include wave nature ferromagnetic domain walls. Specifically, we obtain an explicit equation for magnetic field required move a 180\ifmmode^\circ\else\textdegree\fi{} wall across planar defect such as grain boundary. Using this expression, been able classify successfully both low- and high-coercive-force materials.
