Organic semiconductors constitute promising candidates toward large-scale electronic
circuits that are entirely spintronics-driven. Toward this goal, tunneling magnetoresistance
values above 300% at low temperature suggested the presence of highly spin-polarized
device interfaces. However, such spinterfaces have not been observed directly, let alone at
room temperature. Thanks to experiments and theory on the model spinterface between
phthalocyanine molecules and a Co single crystal surface, we clearly evidence a highly …

Toward the design of large-scale electronic circuits that are entirely spintronics-driven,
organic semiconductors have been identified as a promising medium to transport
information using the electron spin. This requires a ferromagnetic metal-organic interface
that is highly spin-polarized at and beyond room temperature, but this key building block is
still lacking. We show how the interface between Co and phthalocyanine molecules
constitutes a promising candidate. In fact, spin-polarized direct and inverse photoemission …
