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...
