説明
<jats:title>ABSTRACT</jats:title><jats:p>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 0.45<jats:italic>μB</jats:italic>. Rh<jats:sub>13</jats:sub> and Rhl 9 clusters in Ni matrix have lower magnetic moments compared with the free ones. The most interesting finding is tha.t Rh<jats:sub>43</jats:sub> cluster, which is bulk-like nonmagnetic in vacuum, becomes ferromagnetic when embedded in the nickel host.</jats:p>
