Detailed studies of the structure of magnetic nanoclusters are crucial for understanding their magnetic properties. We have investigated the structure of CoxAg1−x nanoparticles by means of molecular dynamics simulations utilizing the embedded atom method. Starting from a completely random distribution of Co and Ag atoms, the clusters were heated up to 1300 K and subsequently cooled down. The size of the resulting particles was 2.8 nm (864 atoms). A clear segregation of the
Ag atoms on the surface of the Co core was obtained.
