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