| Abstract;In the last meeting, we reported the results of dielectric measurements of ferroelectric TGS as a function of temperature at several constant pressures. The Curie temperatureTC increased monotonously with increasing pressure up to about 1.8GPa, and then gradually decreased to about 2.4GPa, at which it suddenly dropped. We have measured the dielectric constant as a function of pressure at several constant temperatures up to 390K. It was found that the boundary between the ferroelectric phase and the new high pressure phase at about 2.5GPa at room temperature is elongated to separate the paraelectric phase from the high pressure phase at higher temperatures.
