We have measured the real components of the third-order optical nonlinearity of organometallic compound films of C60M2 (M = Pd, Pt, and Sm) by using the femtosecond optically heterodyned optical Kerr effect at 647.0 nm. The results show that there is an enhancement of the real components of the third-order optical nonlinearity of C60M2 films compared to that of pristine C-60 film. We attribute the origin of this enhancement to the charge transfer from the metal atoms to the C-60 molecules.
