  We present the results of the density functional theory study of Co_n Mo_m
nanoclusters with n+m=x and 2<=x<=6 atoms on the all-electron level using the
generalized gradient approximation. The discussion of the properties of the
pure cobalt and molybdenium cluster is followed by an analysis of the
respective mixed clusters of each cluster size x. We found that the magnetic
moment of a given cluster is mainly due to the Co content and increases with
increasing n. The magnetic anisotropy on the other hand becomes smaller for
larger magnetic moments S. We observe an increase in the binding energy,
electron affinity, and average bond length with increasing cluster size as well
as a decrease in the ionization potential, chemical potential, molecular
hardness and the HOMO-LUMO gap.
