“…(100). We observe that MnPc and TbPc 2 adsorb flat on metal as well as on metal-oxide surfaces, in agreement with previous studies on related systems [61,62]. The FM and AFM films have an rms roughness smaller than 1.8 Å and present an islandlike morphology [56,63].…”

“…34 Consistently with previous reports, [35][36][37] the XAS of CuPc, shown in Fig. 2͑a͒, feature two main lines separated by about 20 eV, reflecting the transitions from the Cu 2p 1/2,3/2 manifolds into an empty orbital with predominant 3d x 2 −y 2 character.…”

Giant spin and orbital moment anisotropies of a Cu-phthalocyanine monolayer

The magnetism of a Cu-phthalocyanine ͑CuPc͒ monolayer on Ag͑100͒ was investigated using x-ray magnetic circular dichroism ͑XMCD͒ and ligand-field multiplet calculations. Contrary to other metal-Pc adsorbed on metals, we show that the local CuPc moment survives the interaction with the electronic states of the substrate and presents enhanced susceptibility with respect to bulk powder samples. Our measurements reveal extraordinary orbital moment anisotropy ͑500%͒ and an anisotropic spin dipole moment up to twice the isotropic spin in a metal-organic layer. A complete description of the orbital, spin, and spin-orbit operators is provided based on the XMCD sum rules.

“…[15] According to previous results [16][17][18][19][20] obtained for Cu-phthalocyanine (CuPc), the XAS spectrum comprises two main peaks at the L 3 and L 2 edge, respectively. The two main peaks indicate transitions from the spin-orbit split 2p states into the single 3d hole with mainly d x 2 Ày 2 character.…”

Beyond the Heisenberg Model: Anisotropic Exchange Interaction between a Cu-Tetraazaporphyrin Monolayer andFe3O4(100)

The exchange coupling of a single spin localized at the central ion of Cu-tetraazaporphyrin on a magnetite(100) surface has been studied using x-ray magnetic circular dichroism (XMCD). Sum rule analysis of the XMCD spectra results in Cu spin and orbital magnetic moments as a function of the applied external field at low temperatures (20 K). The exchange coupling is positive for magnetization direction perpendicular to the surface (ferromagnetic) while it is negative for in-plane magnetization direction (antiferromagnetic). We attribute the anisotropy of the Heisenberg exchange coupling to an orbitally dependent exchange Hamiltonian.
