Abstract
The temperature dependences of the spontaneous polarization of triglycine selenate (TGSe)–deuterated triglycine selenate (DTGSe) system were measured at several hydrostatic pressures p and DTGSe concentrations x , and the tricritical lines in the p - x plane were determined. It is found that two tricritical lines exist in TGSe-DTGSe system, and are confluent at p =2±1 kbar, x =0.38±0.1 and T =32±2.5°C. This confluent point is the first example of the tetracritical point in ferroelectrics.
