量子反常霍尔效应是指在没有施加磁场的情况下霍尔效应的量子化。量子反常霍尔效应具有拓扑性质，非常适合利用无耗散手性边缘传输的无场电阻计量和低功耗信息处理。在本视角中，我们概述了与工程内在/界面磁耦合相关的最新成就以及材料挑战和机遇，这些挑战和机遇预计将推动该领域的未来发展。 (C) 2022 作者。
The quantum anomalous Hall effect refers to the quantization of the Hall effect in the absence of an applied magnetic field. The quantum anomalous Hall effect is of topological nature and well suited for field-free resistance metrology and low-power information processing utilizing dissipationless chiral edge transport. In this Perspective, we provide an overview of the recent achievements as well as the material challenges and opportunities, pertaining to engineering intrinsic/interfacial magnetic coupling, that are expected to propel future development in this field.
