✦ Synopsis

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 balance between intra-and interatomic exchange and correlation. The enhancement of magnetic moments is analysed in terms of cluster symmetry. Finally, the present results are compared with other theoretical calculations obtained for these systems.
