We study how the structural and magnetic properties of CoRh clusters depend on their size and relative composition. The structures of these clusters are taken from Molecular Dynamics Simulations. The electronic and magnetic properties are calculated with a parametrized Hubbard Hamiltonian. We show that the magnetic moment is not a linear function on their relative composition. The effect of size reduction keeps magnetic order beyond the 50% Rh composition and the Co atoms retain a large magnetic moment in almost the full range.
