The layered antiferromagnet CrSBr is a promising Van der Waals material due to its quasi 1D nature and the strong coupling between excitons, phonons and magnons. In particular, the strong coupling of excitons to the magnetic order of the crystal opens new avenues for the study of correlated magnetic phases in optical spectroscopy. In this work, we perform magneto-optical spectroscopy on multilayer CrSBr. We use Photoluminescence and Reflectivity measurements to identify the different magnetic phases present in the sample. We report drastic changes of the emission and absorption depending on the magnetic phase of the material, which we control through the application of magnetic fields along specific directions.
