我们用同步辐射光电子发射显微镜观察了镍介观磁性结构的磁畴。采用电子束光刻结合化学剥离工艺制备了镍的介观磁性结构。Ni介观样品的几何形状为正方形、三角形和六边形，尺寸分别为5 μ m和10 μm。通过将在Ni L3边缘处测量的图像除以在Ni L2边缘处测量的图像，清楚地观察到磁畴结构。结合磁力显微镜和微磁学模拟的结果，讨论了Ni介观结构的磁畴结构。
We have observed magnetic domains of mesoscopic magnetic structures of Ni by synchrotron radiation photoelectron emission microscopy using circularly polarized soft X-rays from the bending magnet. The mesoscopic magnetic structures of Ni were fabricated by electron beam lithography combined with a chemical liftoff process. The geometries of the Ni mesoscopic samples were square, triangular and hexagonal with the sizes of 5 and 10 μm. The magnetic domains structures were clearly observed by dividing the images measured at the Ni L3-edge by the images measured at the Ni L2-edge. The magnetic domains of the Ni mesoscopic structures are discussed with the results of magnetic force microscopy and micromagnetic simulation.
