Abstract
The electronic and the magnetic properties of Co-Phthalocyanine (CoPc) molecules are modified at the interface with a magnetic metallic surface: upon adsorption of CoPc on iron film relevant changes are observed in the C1s photoemission line shape and on Co L2,3 edges, and N K edge X-ray absorption spectra. X-ray magnetic circular dichroism show Co 3d spin-polarized states i.e. magnetic coupling with the iron substrate at room temperature. The understanding of the interplay among the electronic and magnetic properties of the CoPc adsorption sites, is fundamental for tailoring the functionalities of hybrid organic-metallic interfaces.File | Dimensione | Formato | |
