We have used magneto-reflectance spectroscopy to compare the Zeeman splitting of MoS2 monolayers with that of MoS2 doped with transition metals. At T = 7K we find that the A-exciton Zeeman splitting in the doped sample is 23% higher that of the undoped MoS2. The enhancement is attributed to exchange interaction between the spins of carriers and those of the transition metal ions.
