Magneto-optical reflection spectroscopy on graphene/Co in the soft x-ray range
Original language description
The existence of ferromagnetic ordering in graphene on cobalt is demonstrated by means of resonant magnetic reflection spectroscopy exploiting the transversal magneto-optical Kerr-effect (T-MOKE). Using linearly polarized synchrotron radiation in the soft x-ray range with energies spanning the carbon 1s edge, the pi- and sigma- bonds of graphene were excited individually, showing that magnetism in graphene is carried by the pi - orbitals. Magnetic signals were detected over a wide energy range from 257 - 340 eV with a T-MOKE peak value of 1.1 % at the pi - resonance energy near 285 eV. By comparison with corresponding spectra measured at the 2p edges of the Co substrate, a large induced magnetic moment of 0.14 mu(B) was derived for graphene. Individual hysteresis curves monitored at the Co 2p and C 1s edges show that the carbon magnetism is induced by the Co substrate.
