Direct observation of the basic mechanisms of Pd island nucleation on Au(111)
C. S. Casari, S. Foglio, F. Siviero +3
The formation mechanisms of evaporated Pd islands on the reconstructed Au(111) herringbone surface have been here studied by Scanning Tunneling Microscopy (STM…
Image charge screening: a new approach to enhance magnetic ordering temperatures
S. Altieri, M. Finazzi, H. H. Hsieh +8
We have tested the concept of image charge screening as a new approach to enhance magnetic ordering temperatures and superexchange interactions in ultra thin films. Using a 3 monol…
Low-frequency modes in the Raman spectrum of sp-sp2 nanostructured carbon
C. S. Casari, A. Li Bassi, A. Baserga +8
A novel form of amorphous carbon with sp-sp2 hybridization has been recently produced by supersonic cluster beam deposition showing the presence in the film of both polyynic and cu…
Investigation of sp carbon chain interaction with silver nanoparticles by Surface Enhanced Raman Scattering
A. Lucotti, C. S. Casari, M. Tommasini +8
Surface Enhanced Raman Spectroscopy (SERS) is exploited here to investigate the interaction of isolated sp carbon chains (polyynes) in a methanol solution with silver nanoparticles…
Bulk Cr tips for scanning tunneling microscopy and spin-polarized scanning tunneling microscopy
A. Li Bassi, C. S. Casari, D. Cattaneo +9
A simple, reliable method for preparation of bulk Cr tips for Scanning Tunneling Microscopy (STM) is proposed and its potentialities in performing high-quality and high-resolution…
Exchange-induced frustration in Fe/NiO multilayers
N. Rougemaille, M. Portalupi, A. Brambilla +5
Using spin-polarized low-energy electron microscopy to study magnetization in epitaxial layered systems, we found that the area vs perimeter relationship of magnetic domains in the…
