Abstract

The electronic structure and magnetic properties of rhodium clusters with sizes of 1 - 43 atoms embedded in the nickel host are studied by the first-principles spin-polarized calculations within the local density functional formalism. Single Rh atom in Ni matrix is found to have magnetic moment of 0.45μ_B. Rh₁₃ and Rh₁₉ clusters in Ni matrix have lower magnetic moments compared with the free ones. The most interesting finding is that Rh₄₃ cluster, which is bulk-like nonmagnetic in vacuum, becomes ferromagnetic when embedded in the nickel host.
