Monolayer transition metal dichalcogenides (TMDs) exhibit several fascinating properties. These characteristics can be further expanded by creating heterostructures with CrSBr. CrSBr is an antiferromagnetic semiconductor which exhibits promising magnetic interactions with monolayer TMDs. The magnetic order of CrSBr influences the optical properties of MoSe2 and WSe2, facilitating charge transfer processes [1,2]. This work investigates CrSBr/TMD heterostructures using low-temperature optical spectroscopy with applied magnetic fields to probe excitonic properties. Understanding the optical and valley properties of CrSBr/TMD heterostructures will be relevant for the development of spintronic and valleytronic devices and show a great potential for light harvesting and enhancement of emission from 2D-materials.
