N1  - This work is funded by the DFG (SFB 668-A5, SPP1243 and GrK 611), the JSPS, Alexander von Humboldt foundation, the EU project SpiDME. The computations were performed on JUROPA and JUGENE supercomputers at the Julich Supercomputing Centre, Forschungszentrum Julich (Germany).
AB  - We investigate the spin- and energy-dependent tunneling through a single organic molecule (CoPc) adsorbed on a ferromagnetic Fe thin film, spatially resolved by low-temperature spin-polarized scanning tunneling microscopy. Interestingly, the metal ion as well as the organic ligand show a significant spin dependence of tunneling current flow. State-of-the-art ab initio calculations including also van der Waals interactions reveal a strong hybridization of molecular orbitals and substrate 3d states. The molecule is anionic due to a transfer of one electron, resulting in a nonmagnetic (S = 0) state. Nevertheless, tunneling through the molecule exhibits a pronounced spin dependence due to spin-split molecule-surface hybrid states.
