Artificial van der Waals (vdW) heterostructures composed of semiconducting monolayer transition metal dichalco-genides (TMDs) on the different types of materials such as metallic, superconducting, and magnetic materials have been attractive platforms for emerging novel optical prop-erties. However, the systematic optical studies of vdW het-erostucture composed of semiconducting monolayer TMDs and magnetic-transport phase transition materials have not been reported until now. In this study, we have investigated the charge transfer and magnetic proximity effect for the optically generated excitonic states (excitons and trions) in semiconducting monolayer MoSe2 (1L-MoSe2), and strongly correlated electron system of double-layered perovskite Mn oxide ((La0.8Nd0.2)1.2Sr1.8Mn2O7) vdW heterostucture.
