  Coupling graphene's excellent electron and spin transport properties with
higher spin-orbit coupling material allows tackling the hurdle of spin
manipulation in graphene, due to the proximity to van-der-Waals layers. Here we
use magneto transport measurements to study the electron spin resonance on a
combined system of graphene and MoS2 at 1.5K. The electron spin resonance
measurements are performed in the frequency range of 18-33GHz, which allows us
to determine the g-factor in the system. We measure average g-factor of 1.91
for our hybrid system which is a considerable shift compared to what is
observed in graphene on SiO2. This is a clear indication of proximity induced
SOC in graphene in accordance with theoretical predictions.
