description: This work is dedicated to the experimental study of the ultrafast laser-induced dynamics of the magneto-optical response in low-dimensional magnetically ordered materials. Ultrathin flakes of transition metal thiophosphate NiPSâ have been selected as a research object. The main experimental technique used in the study is femtosecond time-resolved optical pump-probe spectroscopy. During the investigation, the following results have been obtained: - Characteristic relaxation times of laser-induced processes have been determined, obtained values are consistent with data reported in literature. - Features of the laser-induced dynamics in both bulk and thin flakes of NiPSâ are temperature-dependent. - Multiple measurements revealed differences in the laser-induced dynamics in various points located in one area of the sample. This can lead us to the conclusion that magnetooptical response in layered magnetically ordered materials is sensitive to the number of layers and inhomogeneities of the surface even in relatively thick flakes. Low-dimensional magnetically ordered materials are a promising basis for ultra-thin spintronic and electronic devices development and can also be used to create heterostructures with unique properties.
