Van der Waals (vdW) heterostructures composed of two-dimensional (2D)transition metal dichalcogenides (TMD) and vdW magnetic materials offer anintriguing platform to functionalize valley and excitonic properties innon-magnetic TMDs. Here, we report magneto-photoluminescence (PL)investigations of monolayer (ML) MoSe$_2$ on the layered A-typeantiferromagnetic (AFM) semiconductor CrSBr under different magnetic fieldorientations. Our results reveal a clear influence of the CrSBr magnetic orderon the optical properties of MoSe$_2$, such as an anomalous linear-polarizationdependence, changes of the exciton/trion energies, a magnetic-field dependenceof the PL intensities, and a valley $g$-factor with signatures of an asymmetricmagnetic proximity interaction. Furthermore, first principles calculationssuggest that MoSe$_2$/CrSBr forms a broken-gap (type-III) band alignment,facilitating charge transfer processes. The work establishes thatantiferromagnetic-nonmagnetic interfaces can be used to control the valley andexcitonic properties of TMDs, relevant for the development of opto-spintronicsdevices.
