Effect of internal pressure on incipient ferroelectricity of nanoconfined water molecules observed in hydrothermally grown beryl crystals
Original language description
Quasistatic dielectric permittivity of D2O type I molecules within hydrothermally grown beryl crystals characterized by different internal pressure and content of D2O type II molecules is measured at temperatures 4–300 K. All crystals are found to display quantum paraelectric behavior of the D2O-I molecular subsystem permittivity, that is, permittivity growth while cooling from room temperature followed by saturation below 15–40 K. Processing the data with the Barrett expression shows that excess internal pressure and excess content of D2O-II molecules lead to an increase in quantum temperature T1 and a decrease in the Curie constant C, with the Curie temperature TC remaining unchanged. The discovered strengthening of quantum effects (growth of T1) within an ensemble of dipole–dipole-coupled D2O-I mol ecules is associated with an enhanced azimuthal tunneling of these molecules within the hexagonal localizing potential.
