摘要
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.
