摘要

最近在层状反铁磁性半导体 CrSBr 中发现了自旋-激子和磁子-激子耦合，这一发现从根本上讲既引人入胜，又具有重要的技术意义。这一发现揭示了利用激子光学获取和操纵自旋信息的独特能力，为量子互连、量子光子学和光自旋电子学的应用打开了大门。尽管自旋-激子和磁子-激子耦合材料具有非凡的潜力，但它们的应用仍然有限。为了扩大此类材料的资料库，我们探索了实现和调整自旋-激子和磁子-激子耦合的关键参数。我们首先研究了 CrSBr 的耦合机制，并与最近发现的其他二维磁性半导体进行了比较。此外，我们还提出了自旋-外激子耦合的各种可行方案，为未来的研究工作奠定了基础。

Important Elements of Spin-Exciton and Magnon-Exciton Coupling

The recent discovery of spin-exciton and magnon-exciton coupling in a layered antiferromagnetic semiconductor, CrSBr, is both fundamentally intriguing and technologically significant. This discovery unveils a unique capability to optically access and manipulate spin information using excitons, opening doors to applications in quantum interconnects, quantum photonics, and opto-spintronics. Despite their remarkable potential, materials exhibiting spin-exciton and magnon-exciton coupling remain limited. To broaden the library of such materials, we explore key parameters for achieving and tuning spin-exciton and magnon-exciton couplings. We begin by examining the mechanisms of couplings in CrSBr and drawing comparisons with other recently identified two-dimensional magnetic semiconductors. Furthermore, we propose various promising scenarios for spin-exciton coupling, laying the groundwork for future research endeavors.
