摘要: 笼目晶格具有高度对称的六角形网状结构, 因这种独特的几何构型, 其展现出多种新奇的量子特性。笼目晶格材料容易引发自旋的几何阻挫, 进而可能催生量子自旋液体, 并导致拓扑磁畴、非平庸能带结构以及拓扑超导等现象。正因为如此, 笼目晶格体系被认为是探索前沿量子物理和开发未来量子器件的重要平台。本文以不同物理性质为切入点, 对磁性笼目晶格的研究进展作了系统性梳理, 着重介绍了笼目晶格材料的拓扑磁畴结构和拓扑能带等物理现象的最新研究成果, 总结了不同材料体系中笼目晶格的结构与物性特征, 并对其未来发展方向进行了展望。

Abstract: The Kagome lattice possesses a hexagonal network structure with high symmetry. Due to this unique geometric configuration, it exhibits a variety of novel quantum properties. Kagome lattice materials are prone to causing geometric spin frustration, which may give rise to quantum spin liquids and induce phenomena such as topological magnetic domain structures, topological band structures, and topological superconductivity. Consequently, Kagome lattice systems are regarded as vital platforms for exploring frontier quantum physics and developing future quantum devices. This article systematically reviews the research progress of magnetic Kagome lattices from different physical properties. It focuses on the latest research achievements regarding topological magnetic domains and topological bands in Kagome lattices, summarizes the structural and physical characteristics of Kagome lattices in various material systems, and provides an outlook on future prospects of the field.

Key words: Kagome lattice, topological magnetic domain structure, topological band
