Ultrathin epitaxial cobalt films formed under graphene

摘要: The intercalation of cobalt under a graphene monolayer grown on Ni(111) single crystal film is studied. experiments are conducted in ultrahigh vacuum. Samples characterized situ by low energy electron diffraction, high-energy-resolution photoelectron spectroscopy using synchrotron radiation, and magnetic linear dichroism photoemission Co 3p electrons. New data obtained the evolution atomic electronic structure properties system with increasing thickness intercalated layer range up to 2 nm. It shown that pseudomorphic epitaxial Co(111) having magnetization perpendicular surface formed grapheme during an anomalously wide thicknesses.
