A microscopic model for charge disordered relazor systems
A microscopic relaxor model is described and its properties are studied by means of numerical simulations. No a priori random interactions neither random fields are considered. The solely interaction of mobile charges with the dipoles of a highly polarizable medium is responsible for the appearance of typical relaxor properties such as a smeared transition, a glassy ground state with no macroscopic polarization, a external field frequency dependent dielectric constant and a field induced ferroelectric behavior.
