Abstract
Monte Carlo (MC) simulation is performed for samples modeled on OH - :KCl to show that the electric dipole-dipole interaction H d d leads freezing of permanent electric dipoles distributed randomly in dielectrics. Frustration due to H d d yields a huge number of metastable states as in spin glasses. Although the result for the dielectric constant shows a rounded maximum in the temperature dependence, no sign can be found in the order parameter q corresponding to the maximum of the dielectric constant. In fact q remains finite up to high temperature. As far as the simulation is limited to 1000 MC steps per moment, the electtic moments seem to freeze gradually with decreasing temperature by growing cluster size. This contrasts sharply with the behavior in the Sherrington-Kirkpatrick spin glass where a considerably clear sign for the phase transition can be found in MC simulation.
