The magnetic and magneto-optial properties of rf sputter-deposited layer-modulated Co/Pt multilayers with Cu and Ag interlayers were investigated. The multilayers in which each Co layer is sandwiched between Pt layers exhibit perfect squareness in the polar Kerr hysteresis. In the Co/Pt multilayers with Cu interlayers, the Kerr rotation angle has a maximum at a wavelength of 600 nm for 50Å Cu thickness.
