Magneto-optical effects of TbFeCo/NdCo and TbFeCo/Pt multilayer films and NdTbFeCo alloy films prepared by sputter deposition are discussed in conjunction with the multilayer structure and the composition. The contribution to the polar Kerr spectra due to NdCo and Pt layers is significantly found at ultraviolet photon energies for both cases. In TbFeCo/NdCo multilayers, it is found that the enhancements of Kerr rotation θ_k and ellipticity η_k increase with NdCo layer thickness and become saturated at t_<NdCo>=15Å for the case of t_<TbFeCo>=30Å. In TbFeCo/Pt multilayer, the θ_k and η_k are also enhanced with Pt layer thickness and become saturated at t_<Pt>=12Å.
