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.Work was supported by the European Research Council (Starting Grant No. 203239 NOMAD), European Science Foundation (EUROCORES SANMAG), the Spanish Ministerio de Ciencia e Innovación (Grant No. MAT2007-62341), the Catalan Agència de Gestió d’Ajuts Universitaris i de Recerca (2009 SGR 695), and Italian MIUR (Grant No. PRIN 20087NX9YT).Peer reviewedAmerican Physical SocietyEuropean Research CouncilEuropean Science FoundationMinisterio de Ciencia e Innovación (España)Generalitat de Catalunya201220122010info:eu-repo/semantics/articlehttp://purl.org/coar/resource_type/c_6501http://hdl.handle.net/10261/44564reponame:DIGITAL.CSIC.
