Abstract
The critical exponent ratio beta/gamma = 0.46 +/- 0.01 has been obtain ed for TGSe from the measurements of electric susceptibility at non-ze ro electric fields in the paraelectric phase. The stronger deviations from Landau critical and tricritical theories as well as from Larkin-K hmelnitskii model have been shown. A generalized form of Larkin-Khmeln itskii equation of state is deduced from the experimental data for TGS e ferroelectric.
