Epitaxial graphene/ferromagnetic metal (Gr/FM) heterostructures depositedonto heavy metals (HM) have been proposed for the realization of novelspintronic devices because of their perpendicular magnetic anisotropy andsizeable Dzyaloshinskii-Moriya interaction (DMI), allowing for both enhancedthermal stability and stabilization of chiral spin textures. However,establishing routes towards this goal requires the fundamental understanding ofthe microscopic origin of their unusual properties. Here, we elucidate thenature of the induced spin-orbit coupling (SOC) at Gr/Co interfaces on Ir.Through spin- and angle-resolved photoemission along with density functionaltheory, we show that the interaction of the HM with the C atomic layer viahybridization with the FM is the source of strong SOC in the Gr layer.Furthermore, our studies on ultrathin Co films underneath Gr reveal an energysplitting of $\sim$\,100 meV (negligible) for in-plane (out-of-plane) spinpolarized Gr $\pi$ bands, consistent with a Rashba-SOC at the Gr/Co interface,which is either the fingerprint or the origin of the DMI. This mechanismvanishes at large Co thicknesses, where neither in-plane nor out-of-planespin-orbit splitting is observed, indicating that Gr $\pi$ states areelectronically decoupled from the HM. The present findings are important forfuture applications of Gr-based heterostructures in spintronic devices.
