In this paper the magneto-optical polar Kerr rotation spectra of composition-ally modulated films(CMF)Co/Pt are calculated by using Fresnel’s equations.For CMF Co/Pt with d_(Co)/d_(pt)=1/2,1 and 2 the magneto-optical Kerr rotation at any wavelength increases with the increasing modulation wavelength in the wavelength region from 200 to 800nm.For CMF Co/Pt of constant d_(pt) the Kerr rotation increases with d_(Co) increasing while of constant d_(Co) the Kerr rotation increases with d_(pt) decreasing.From numerical calculations it is suggested that for CMF Co/Pt with small d_(pt) the Pt sublayer is polarized and has a positive contribution to the Kerr rotation of CMF Co/Pt.
