具有磁性手征的非平凡自旋序出现在具有结构手征的特定类别的磁性材料中，其通常被称为手征磁体。通过手征磁序与传导电子和电磁场的耦合，有望在手征磁体中诱导出各种有趣的物理性质。实现这些耦合的一个有希望的候选者是手征自旋孤子晶格。在这里，我们回顾了最近的实验观察主要是通过使用电子，中子和X射线束的磁成像和磁阻测量单轴手性磁性晶体CrNb3S6，与合成手性磁性材料的策略和相关的理论背景。在垂直于手征螺旋轴的磁场作用下，手征孤子晶格在宏观尺度上具有很强的稳定性和相位相干性。研究了手征孤子晶格的可调谐性和拓扑性质。
Nontrivial spin orders with magnetic chirality emerge in a particular class of magnetic materials with structural chirality, which are frequently referred to as chiral magnets. Various interesting physical properties are expected to be induced in chiral magnets through the coupling of chiral magnetic orders with conduction electrons and electromagnetic fields. One promising candidate for achieving these couplings is a chiral spin soliton lattice. Here, we review recent experimental observations mainly carried out on the monoaxial chiral magnetic crystal CrNb3S6 via magnetic imaging using electron, neutron, and X-ray beams and magnetoresistance measurements, together with the strategy for synthesizing chiral magnetic materials and underlying theoretical backgrounds. The chiral soliton lattice appears under a magnetic field perpendicular to the chiral helical axis and is very robust and stable with phase coherence on a macroscopic length scale. The tunable and topological nature of the chiral soliton lattic...
