The magnetic properties of icosahedral clusters are studied using the discrete-variational local-spin-density-functional method, where M = V, Cr, Mn, Fe, Co, and Ni. The results show that all of the clusters, just like the case for the cluster, have double magnetic solutions. In contrast to the moment of for the cluster, the total magnetic moments of the clusters, ranging from to , have been changed greatly by the substitution of the central Ru atom with M. Among them, the cluster has a giant moment of . Furthermore, the cluster has nondegenerate ground state and could be expected to be remark...
