Substrate induced spin polarization was observed in molecular layers of C24H36N2O4Cu (Cu(CNdpm)2) deposited on cobalt (111). Extra molecular interactions between these Cu 1/2 molecules and the ferromagnetic substrate are implicated while the Cu(CNdpm)2 molecular layers have an opposite spin polarization compared to the Co(111) substrate near the Fermi edge. The spin-polarized photoemission results are seen to be consistent with magnetometry and mean field (Ginzburg-Landau) models. The spin asymmetry favors select molecular orbitals, suggesting that the local spin 1/2 moment of copper is enhanced by contributions from select molecular orbitals.
