N2 - We examine a simple model of Pb(In1/2Nb1/2)O 3 (PIN), which includes both long-range dipole-dipole interaction and random local anisotropy. An improved algorithm optimized for long-range interaction has been applied to efficient large-scale Monte Carlo simulation. We demonstrate that the phase diagram of PIN is qualitatively reproduced by this minimum model. Some characteristic features of relaxors such as nanoscale domain formation, slow dynamics, and dispersive dielectric responses are also examined.
