Magnetic exchange coupling of a synthetic Co(ii)-complex to a ferromagnetic Ni substrate

On-surface assembly of a spin-bearing and non-aromatic porphyrin-related synthetic Co( ii )-complex on a ferromagnetic Ni thin film substrate and subsequent magnetic exchange interaction across the interface were studied by scanning tunnelling microscopy (STM), X-ray absorption spectroscopy (XAS), X-ray magnetic circular dichroism (XMCD) and density functional theory + U (DFT + U ) calculations. Ferromagnetic coupling of a synthetic porphyrin-related complex of Co( ii ) with C 2v symmetry to a ferromagnetic Ni substrate is demonstrated.
