Orbital Polarization, Surface Enhancement and Quantum Confinement in Nano-cluster Magnetism
Within a rather general tight-binding framework, we studied the magnetic properties of Nin clusters with n = 9 through 60. In addition to usual hopping, exchange, and spin-orbit coupling terms, our Hamiltonian also included orbital correlation and valence orbital shift of surface atoms. We show that orbital moment not only contributes appreciably to the total moment in this range of cluster siz...
متن کاملGeometric and Electronic Structures of Vanadium Sub-nano Clusters, Vn (n = 2-5), and their Adsorption Complexes with CO and O2 Ligands: A DFT-NBO Study
In this study, electronic structures of ground state of pure vanadium sub-nano clusters, Vn (n=2-5), and their interactions with small ligands for example CO and triplet O2 molecules are investigated by using density functional theory (DFT) calibration at the mPWPW91/QZVP level of theory. The favorable orientations of these ligands in interaction with pure vanadium sub-nano clusters were determ...
متن کاملOrbital magnetism in transition-metal systems: The role of local correlation effects
The influence of correlation effects on the orbital moments for transition metals and their alloys is studied by first-principle relativistic Density Functional Theory in combination with the Dynamical Mean-Field Theory. In contrast to the previous studies based on the orbital polarization corrections we obtain an improved description of the orbital moments for wide range of studied systems as ...
متن کاملOrbital magnetism of transition-metal adatoms and clusters on the Ag and Au„001... surfaces
We present ab initio calculations of the orbital moments and magnetocrystalline anisotropy energies for 3d , 4d , and 5d transition-metal adatoms and for some selected small clusters on the ~001! surfaces of Ag and Au. The calculations are based on the local density approximation of density functional theory and apply a fully relativistic Koringa-Kohn-Rostoker Green’s function method. Due to th...
متن کاملRole of Co in enhancing the magnetism of small Fe clusters
Using ab initio calculations, we study the magnetic features of the FemCon, m+n 6 clusters and investigate the role of Co in enhancing the magnetism of the Fe grains. Our results show that the role of Co appears to be that of inducing structural changes in the grain which may lead to enhanced magnetic moments for the Co-Fe clusters as a result of the rehybridization process and the following re...
