利用新研制的自旋极化扫描电子显微镜，我们成功地获得了层状结构锰氧化物La1.4Sr1.6Mn2O7中反铁磁态与1 nm台阶原子平台共存的实空间图像.自旋取向的三维分析可以进一步揭示温度相关的自旋重取向和原子台阶上的反铁磁畴壁。这些确保了使用本显微镜在更广泛的材料，包括磁性氧化物和纳米材料的局部磁结构的定量分析。
With the use of a newly developed spin-polarized scanning electron microscope, we have succeeded in obtaining the real-space images of the layered-antiferromagnetic state concurrent with 1-nm-stepped atomic terraces in layered-structure manganite La1.4Sr1.6Mn2O7. The three-dimensional analysis of spin alignment could further reveal the temperature-dependent spin reorientation and the anfiferromagnetic domain walls on the atomic terraces. These ensure the use of the present microscopy for quantitative analysis of local magnetic structures in a broader range of materials, including magnetic oxides and nanomaterials.
