新型拓扑磁光材料研究进展OA
Research Progress on Novel Topological Magneto-Optical Materials
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.
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.
