The magnetism of bimetallic CoxM1-x (M: Ru and Rh) clusters has been investigated on systems of nanoparticles with diameters smaller than 2nm embedded in a polymer obtained by means of organometallic synthesis. Whatever the composition (up to x=0.75), the investigation of magnetism evidence a ferromagnetic behavior. As a consequence of size reduction, both CoRh and CoRu systems display enhanced magnetic moments and anisotropy compared to bulk values.
