Abstract： In this paper single layer NdFe film, bilayer NdFe/Cu and NdFe/Al films made by vacuum evaporation were studied. The magneto-optical Kerr effect(MOKE) and reflectivity spectra were measured. The following results were found: the contribution of Nd to MOKE is mainly at short wavelengths, for NdFe/Al the MOKE enhancement locates in the short wavelength range and for NdFe/Cu the enhancement peak locates near the absorption edge of reflector Cu, and in the MOKE spectra of bilayer NdFe/Cu film with some compositions, sign reversals were observed.
