Atomically thin, magnetic materials have recently gained a lot of attention in the field of two-dimensional (2D) materials. Single magnetic layers with critical temperature above room-temperature are extremely attractive for fundamental studies and promising candidates for future spintronic applications. However, probing the magnetic order of the 2D systems by conventional magnetic experimental setups is very challenging. On the other hand, it is well known that even in the single layer limit, semiconducting two-dimensional materials strongly absorb light. Therefore, optical spectroscopy is a good method for their characterization. In order to shed light on the intriguing phenomena of 2D antiferromagnets (AFM), I will present our recent theoretical investigations in the framework of the density functional theory (DFT) considering optical properties of the layered materials. In particular, I will focus on the representative AFM family, transition metal phosphorus trisulfides (MPX3), in respect to other 2D materials. I will cover currently puzzling research issues in respect to optical properties of layered materials.
