The results of optical magneto-spectroscopy study (Raman scattering, THz absorption, high frequency magnetic resonance) of layered MnPS3 and FePS3 antiferromagnets will be presented. Attention will be focused on magneto-elastic interaction in MnPS3 [1] and appearance of magnon polarons in FePS3 [2]. Besides, the origin of a magnon gap in MnPS3 and splitting of this gap observed in both...
In the regime of strong light-matter coupling, polariton modes are formed that are hybrid light-matter excitations sharing properties of both, an electrodynamic cavity mode and a matter mode. Recently, magnon-polaritons are intensively researched in ferromagnetic materials in the microwave range, with potential applications for quantum computing and sensors. In the recent decade, polaritons...
