The results of self-consistent nonlocal (GGA) density functional calculations are reported for small cobalt clusters (n)6;13). An emphasis is made on a proper treatment of correlation effects. The magnetic as well as the bonding properties of these clusters are discussed in terms of a delicate balan

✦ Synopsis
Fully self-consistent spin-polarized nonlocal (GGA) Density Functional calculations of small mixed copper-Cobalt systems are performed with confined to their linear structure geometry optimizations.The core electrons of both atoms have been described by a model potential. An important 3p-3d correlations have been taken fully into account by promoting the 3p shells into a valence basis sets. An analysis of essential d-type bonding mechanisms is made by means of Mulliken populations. The bonding/antibonding nature of HOMO-LUMO interface is discussed in detail.

Small clusters of cobalt atoms, Co n (n ≤ 3), were studied with the aid of the program deMon-KS module release 3.2, which is a density functional theory based method. Self-consistent-field model core potential (MCP) calculations, which describe the core electrons of the cobalt atom, were done in con
Small molybdenum clusters up to the tetramer are investigated within the framework of the density functional theory. Both the geometry and the spin state are optimized for the dimer, trimer, and the tetramer. Moreover, all those calculations are followed by a vibrational analysis to discriminate bet
Small nickel clusters up to the tetramer are investigated within the framework of the local spin density functional theory. Several competitive states are studied for the dimer. Both the geometry and the spin state are optimized for several starting symmetries in the case of the trimer and the tetra
We investigate the structural, vibrational, and energetic properties of [Be( HzO),]\*+ clusters with n = 1, 2, 3, 4, and 6 water molecules, relevant to Be \*+ hydration. The Becke exchange gradient-corrected local density approximation is used in the framework of a pseudopotential representation of
