In this work, we study the cobalt radical interface obtained by depositing a monolayer of a derivative of the Blatter radical on polycrystalline cobalt. By examining the occupied and unoccupied states at the interface, using soft X-ray techniques, and combining them with ab initio calculations, we can completely determine the electronic structure at the interface, simultaneously, on both the molecular and ferromagnetic sides, and thus obtain a full understanding of the magnetic properties at the interface. We find that the molecule is strongly hybridized with the surface. Changes in the core level spectra reflect the modification of the molecule and cobalt electronic structure induced by the bonding across the interface. This causes a decrease in the magnetic moments of the cobalt atoms bonded to the molecules that lose their radical character. Our method allows screening, beforehand, the organic ferromagnetic interfaces in view of potential applications in spintronic.
