    "abstract": "A binary system of classical charged particles interacting through a dipole\nrepulsive potential and confined in a two-dimensional hardwall trap is studied\nby Brownian dynamics simulations. We found that the presence of small particles\n\\emph{stabilizes} the angular order of the system as a consequence of radial\nfluctuations of the small particles. There is an optimum in the increased\nrigidity of the cluster as function of the number of small particles. The small\n(i.e. defect) particles melt at a lower temperature compared to the big\nparticles and exhibit a \\emph{reentrant} behavior in its radial order that is\ninduced by the intershell rotation of the big particles.",
