title: Phase separation in model polydisperse ferrofluids.
abstract: The influence of polydispersity on the phase equilibrium properties of a dipolar system with additional short-range (repulsive+attractive) interactions (modeled by a shifted Lennard-Jones pair potential) is studied by means of Gibbs ensemble Monte Carlo simulations. The critical temperature and density as well as the magnetization at the critical point are calculated as a function of the applied magnetic field, and the obtained results are compared with the data determined in a monodisperse equivalent of the system.
