Notes: In this communication, the magneto-optical polar Kerr rotation spectra of multilayers Fe/Pt and Co/Pt are calculated based on two different assumptions. First, the spin polarization of the Pt layer is assumed to be negligible. The calculated results for Fe/Pt and Co/Pt multilayers with dCo(Fe)/dPt=1 showed the magneto-optical Kerr rotation in the region from 300 to 800 nm increased with increasing modulation wavelength, which is opposite to experimental results. Second, the Pt layer is assumed to be polarized and has a direct contribution to Kerr rotation in the multilayers. The results agree with experiments qualitatively. It is found that the spin polarization of the Pt layer increases with decreasing Pt layer thickness.
