| Popis: | We demonstrate the successful preparation of ordered C60 films on Co/Au(111) by scanning tunneling microscopy (STM). In particular, we show that the C60 molecules arrange in a close-packed hexagonal pattern after postdeposition annealing at T = 350 °C. From STM measurements with intramolecular resolution we find domains with different orientational ordering, that is ultimately a result of the lateral arrangement of the C60 molecules on the Co surface. The local ordering of the various domains is also clearly reflected in the measured differential conductance spectra. In particular, we find an energetic shift of the LUMO + 1 due to the reconstruction of the cobalt substrate. Our study opens the way for the introduction of ordered “spinterfaces” in molecular spintronics. |
