| English abstract | We have studied the optimum geometries and the magnetic behavior of small binary ConSim (n + m ≤ 4) clusters using abinitio spin-polarized density functional calculations. Our results reveal, the optimized clusters present magnetic behavior and depends of the number of Si atoms in the cluster, in some cases the local magnetic moments at Co atoms present an enhancement respect to Co bulk magnetization, whereas the Si atoms present local magnetic moments whose modulus take significative values. All the clusters studied here present a charge transference to Si atoms from Co atoms, giving polar characteristics to the clusters |
