“…1͒. For Rh 13 we have the same value as Jinlong whereas for Rh 19 we slightly understimate the magnetic moment, this value of J dd corresponds to the best simultaneous fitting considering the dependence shown in the Fig. 1.…”

“…1,2 None of the 4d and 5d solids are magnetic spontaneously. 2 However, since the 1980's, the experimental growth and characterization of lowdimensional systems ͑surfaces, films, and small clusters͒ [3][4][5][6][7][8][9][10][11][12][13][14] with reduced coordination and symmetry, and relaxed interatomic distances, opens the possibility of stabilizing magnetic phases in certain a priori nonmagnetic 4d and 5d transition metals systems. 5 Examples of experimental evidence for the 4d ferro-magnetism in two-dimensional Ru and Rh structures supported on substrates can be found in Refs.…”

We report a systematic study of the structural and magnetic properties of free-standing rhodium clusters (Rh N , 4рNр26). The geometrical structures of the global minima and lowest energy isomers were obtained with a semiempirical Gupta potential and employing a global evolutive search algorithm. The spin-polarized electronic structure and related magnetic properties of these geometries were calculated by solving selfconsistently a spd tight-binding Hamiltonian. We determined the possible coexistence of different isomers and found that inclusion does not, in general, change significantly the magnetic moments obtained for the global minima structures. Results are compared with the experiment and with other theoretical calculations available in the literature.

“…Among 4d transition metals, bulk paramagnetic elements like Ru, Rh, and Pd exhibit magnetism on surfaces and in nanosystems 35,36,37 . In particular, Pd atoms are not intrinsically magnetic because of the closed shell configuration of the 4d orbitals (4d 10 5s 0 ).…”

We study the effects of metallic doping on the electronic properties of graphene using density functional theory in the local density approximation in the presence of a local charging energy (LDA+U). The electronic properties are sensitive to whether graphene is doped with alkali or transition metals. We estimate the the charge transfer from a single layer of Potassium on top of graphene in terms of the local charging energy of the graphene sheet. The coating of graphene with a non-magnetic layer of Palladium, on the other hand, can lead to a magnetic instability in coated graphene due to the hybridization between the transition-metal and the carbon orbitals.

Recent trends in the emerging field of surface-supported magnetic nanostructures are reviewed. Current strategies for nanostructure synthesis are summarized, followed by a predominantly theoretical description of magnetic phenomena in surface magnetic structures and a review of experimental research in this field. Emphasis is on Fe-or Co-based nanostructures in various low-dimensional geometries, which are studied as model systems to explore the effects of dimensionality, atomic coordination, chemical bonds, alloying and, most importantly, interactions with the supporting substrate on the magnetism. This review also includes a discussion of closely related systems, such as 3d element impurities integrated into organic networks, surface-supported Fe-based molecular magnets, Kondo systems or 4d element nanostructures that exhibit emergent magnetism, thereby bridging the traditional areas of surface science, molecular physics and nanomagnetism.
