In order to obtain a fundamental understanding of the interplay between charge, spin, orbital and lattice degrees of freedom in magnetic materials and to predict and control their physical properties^1,2,3, experimental techniques are required that are capable of accessing local magnetic information with atomic-scale spatial resolution. Here, we show that a combination of electron energy-loss magnetic chiral dichroism⁴ and chromatic-aberration-corrected transmission electron microscopy, which reduces the focal spread of inelastically scattered electrons by orders of magnitude when compared with the use of spherical aberration correction alone, can achieve atomic-scale imaging of magnetic circular dichroism and provide element-selective orbital and spin magnetic moments atomic plane by atomic plane. This unique capability, which we demonstrate for Sr₂FeMoO₆, opens the door to local atomic-level studies of spin configurations in a multitude of materials that exhibit different types of magnetic coupling, thereby contributing to a detailed understanding of the physical origins of magnetic properties of materials at the highest spatial resolution.

为了基本了解磁性材料中电荷，自旋，轨道和晶格自由度之间的相互作用，并预测和控制其物理性质^1,2,3，需要能够访问局部磁信息的实验技术具有原子级的空间分辨率。在这里，我们证明了电子能量损失的磁性手性二向色性^4的组合和色像差校正的透射电子显微镜，与单独使用球面像差校正相比，可以将非弹性散射电子的焦点散布减小几个数量级，可以实现磁圆二色性的原子级成像并提供元素选择的轨道并逐个原子平面旋转磁矩。我们针对Sr ₂ FeMoO ₆展示的这种独特功能为多种材料表现出不同类型的磁耦合的自旋构型的局部原子级研究打开了大门，从而有助于对磁性的物理起源的详细理解。最高空间分辨率下的材料特性。
