Interface structure and magnetic anisotropy of a Co/Pt multilayer

A Co/Pt multiplayer with strong perpendicular magnetic anisotropy is studied by electron beam evaporation of polarized CoK edge EXAFS. The in-plane polarized EXAFS indicate an abrupt interface structure and the abrupt interface structure is probably a surface equilibrium state and can be trapped in the bulk by subsequent deposition without much interdiffusion.
