Dipole ordering of water molecules in cordierite: Monte Carlo simulations

Electric dipoles of water molecules, enclosed singly in regularly spaced nanopores a cordierite crystal, become ordered at low temperature due to their mutual interaction and show the frequency dependence dielectric susceptibility, typical for relaxor ferroelectrics, according recent experimental data. The corresponding phase transition is accompanied by anomalies thermodynamic quantities, such as heat capacity which are calculated here using Monte Carlo method, agreement data discussed. Despite increase correlation length, partially filled dipole lattice temperatures, calculations, does not have long-range order corresponds glass. This simulation gives microscopical insight into formation polar nanoregions ferroelectrics size.
