Atomically thin, magnetic materials have recently gained a lot ofattention in the field of two-dimensional (2D) materials [1]. Singlemagnetic layers with critical temperature above room-temperature areextremely attractive for fundamental studies and promising candidatesfor future spintronic applications. However, probing the magnetic orderof the 2D systems by conventional magnetic experimental setups is verychallenging. On the other hand, it is well known that even in the singlelayer limit, semiconducting two-dimensional materials strongly absorblight. Therefore, optical spectroscopy is a good method for theircharacterization. In order to shed light on the intriguing phenomena of2D antiferromagnets (AFM), I will present our recent theoreticalinvestigations [2-7] in the framework of the density functional theory(DFT) considering optical properties of the layered materials. Inparticular, I will focus on the representative AFM family, transitionmetal phosphorus trisulfides (MPX3), in respect to other 2D materials. Iwill cover currently puzzling research issues in respect to opticalproperties of layered materials.Refs:[1] M. Gibertini, et.al [2] Nat. Nanotech. 14, 408 (2019).[2] M. Birowska, et. al. Phys. Rev.
