我们已经研究了在Ni80Fe20平面纳米线使用磁性软X射线显微镜和微磁学模拟畴壁之间的静磁相互作用。除了显着的类似单极的吸引和排斥效应之外，我们还观察到壁的磁化结构存在耦合。这是解释的相互作用的能量，不仅取决于之间的距离的墙壁，但也对他们的内部磁化结构。
We have investigated magnetostatic interactions between domain walls in Ni80Fe20 planar nanowires using magnetic soft x-ray microscopy and micromagnetic simulations. In addition to significant monopole-like attraction and repulsion effects we observe that there is coupling of the magnetization configurations of the walls. This is explained in terms of an interaction energy that depends not only on the distance between the walls, but also upon their internal magnetization structure.
