论文摘要
我们报告了纳米级磁纹理的空心孔成像和小角度的电子衍射，例如磁条域和M型六边形铁素体Bafe $ _ {10.35} $ sc $ _ {1.6} $ _ {1.6} $ mg $ _ {0.05} $ _ {0.05} $ o $ o $ o $ o $ o $空心碳富康方法的优点是，在Infocus条件下，具有各种磁化方向的磁域可以可视化。此外，磁性气泡中磁性域壁的对比取决于照明束的倾斜角。小角度电子衍射和空心福柯成像的组合证明，域壁上的磁化在磁性域和磁性气泡中显示出平面方向。
We report hollow-cone imaging and small-angle electron diffraction of nanoscale magnetic textures such as magnetic-striped domains and magnetic bubbles of M-type hexagonal ferrite BaFe$_{10.35}$Sc$_{1.6}$Mg$_{0.05}$O$_{19}$. The advantage of the hollow-cone Foucault method is that magnetic domains with various directions of magnetization can be visualized under an infocus condition. Moreover, the contrast of magnetic domain walls in magnetic bubbles depends on the inclination angle of the illumination beam. The combination of small-angle electron diffraction and hollow-cone Foucault imaging proves that magnetization at domain walls exhibits in-plane directions in the magnetic-striped domains and magnetic bubbles.
