Discovery of van der Waals (vdW) magnetic semiconductors with direct bandgaps have created opportunities for investigating light-matter interactions and spintronic applications which are absent in conventional bulk magnets. This talk will show our recent theoretical and computational studies of tunable magnetism and light-matter interactions of few-layer CrSBr. In the first part, we show that the magnetism in CrSBr is highly tunable by strain, pressure, chemical doping, and interfacing with other vdW materials like graphene. This allows for multi-dimensional control of magnetic orders and noncollinear magnetism. In the second part, we demonstrate the strong light-matter interactions and unique excitonic structures in CrSBr provide possibility to control material transparency by ultrafast means. Finally, we connect our theoretical discoveries to experimental results and explore potential applications in spintronics and quantum information science.
