Abstract:

We have computed minimum energy magnetic structure configurations of Mn nanoclusters ranging from 10 to 55 atoms in size. Spin-polarized electronic properties are calculated by solving an spd tight-binding Hubbard like Hamiltonian in the unrestricted Hartree-Fock approximation by using a bulk-like parametrization. Uniform expansions and contractions are done to follow the dependence of magnetization on interatomic distance. The obtained results allow us to infer that close shell icosahedral structures are competitive with bcc-like ones for N=13, 19, 32, and 42, whereas for other N values the bcc (with and without central atom) are the ones with lowest electronic energy reproducing the general experimental behaviour. © 2004 Elsevier B.V.
