摘要: 磁光晶体能保证激光单向传输,广泛应用于非互易光学器件、光隔离器、光开关等器件,在光通信、高功率激光等领域发挥着不可替代作用。目前,以TGG、CeF3、YIG等为代表的传统磁光材料,在紫外、可见光至近红外波段已得到广泛应用。然而,对于日益增长的中红外甚至太赫兹波段的潜在应用需求,目前缺乏综合性能优异的磁光材料。近年来,六方非共线反铁磁Mn3Sn具有独特kagome晶格和拓扑能带结构,被Nature等期刊连续报道。Mn3Sn具有极小的净磁矩,能够产生巨大的磁光克尔效应与反常霍尔效应,在中红外、太赫兹波段等具有应用前景。本文系统梳理了以Mn3Sn晶体为代表的新型拓扑磁光材料的最新研究进展,包括磁光性能、相关调控机理与晶体生长等,为新型磁光材料设计提供有价值的参考。

Abstract: Magneto-optical crystals enable unidirectional laser transmission and are widely used in nonreciprocal optical devices, including optical isolators, optical switches, playing an irreplaceable role in optical communications and high-power lasers. At present, conventional magneto-optical materials such as TGG, CeF3, and YIG have been extensively applied in the ultraviolet, visible, and near-infrared spectral ranges. However, rather limited types of magneto-optical materials fulfill the increasing potential demands for the mid-infrared and even Terahertz ranges. Recently, hexagonal non-collinear antiferromagnets Mn3Sn, featuring unique kagome structure and topological band, have been continuously reported in journals such as Nature. Despite its extremely small net magnetic moments, Mn3Sn exhibits giant magneto-optical Kerr effects and anomalous Hall effects, showing great potential for mid-infrared and terahertz applications. This paper systematically reviews the recent research progress on Mn3Sn crystals, including their magneto-optical properties, relevant modulation mechanisms, and crystal growth, aiming to provide valuable references for the design of novel magneto-optical materials.

Key words: magneto-optical material; topological band structure; mid-infrared waveband; Mn3Sn; non-collinear antiferromagnet
