Abstract
We report the results of spectroscopic magneto-optic polar Kerr rotati on experiments on Au/Au50Co50/Co/Au (111) ultrathin magnetic structure s prepared by evaporation in UHV, with different Co and Au50Co50 thick nesses and perpendicular easy magnetization axes. Previous in situ RHE ED experiments have shown a surfactant effect during Au deposition on Co(0001) in the monolayer range. The spectroscopic MOKE data give new proof that during deposition of the alloy Au50Co50, separation takes p lace between the Au and Co; the Au atoms segregate and grow at the top of the Co layer.
