论文摘要
在我们对众多磁现象的理解中,异常的大厅效应是必不可少的。这涉及铁磁材料以及各种类别的抗铁磁体,除了异常和水晶厅的效应外,在过去几十年中,非流行抗抗铁磁体的拓扑厅效应是非跨乳腺抗fiferromagnets的拓扑作用。在这里,我们在倾斜的旋转系统中发现了一种异常的大厅效应的新风味。使用先进的理论工具,我们证明,在倾斜后,异常的大厅效应获得了一种对旋转中烙印矢量性手性感敏感的贡献。我们探讨了相应的手性霍尔效应的起源和基本特性,并将其与系统的对称属性紧密联系在一起。我们的发现表明,手性厅效应和相应的手性磁光效应是表征复杂磁体中结构和手性相互作用的新型多功能工具,以及跟踪其手性动力学和波动。
The anomalous Hall effect has been indispensable in our understanding of numerous magnetic phenomena. This concerns both ferromagnetic materials, as well as diverse classes of antiferromagnets, where in addition to the anomalous and crystal Hall effects, the topological Hall effect in non-coplanar antiferromagnets has been a subject of intensive research in the past decades. Here, we uncover a new flavour of the anomalous Hall effect in canted spin systems. Using advanced theoretical tools we demonstrate that upon canting, the anomalous Hall effect acquires a contribution which is sensitive to the sense of imprinted vector chirality among spins. We explore the origins and basic properties of corresponding chiral Hall effect, and closely tie it to the symmetry properties of the system. Our findings suggest that the chiral Hall effect and corresponding chiral magneto-optical effects emerge as novel versatile tools in characterizing an interplay of structure and chirality in complex magnets, as well as in tracking their chiral dynamics and fluctuations.
