abstract = {We have studied by means of low-temperature scanning
tunneling microscopy (STM) and spectroscopy (STS) single
molecular spin hybrids formed upon chemisorbing a polycyclic
aromatic, threefold symmetric hydrocarbon molecule on
Co(111) nanoislands. The spin-dependent hybridization
between the Co d states and the π orbitals of the molecule
leads to a spin-imbalanced electronic structure of the
chemisorbed organic molecule. Spin-sensitive measurements
reveal that the spin polarization shows intramolecular
variations among the different aromatic rings in spite of
the highly symmetric adsorption geometry promoted by
symmetry matching of the threefold symmetric molecule and
the sixfold symmetric Co(111) lattice. Hence the varying
degree of spin polarization on the organic molecule does not
stem from a different hybridization of the aromatic rings
with the Co atoms, but is proposed to be a consequence of
the superposition of the spin polarization of the molecule
and the spatially modulated spin polarization of the
spin-dependent quantum interference pattern of the Co(111)
surface state.},
