Abstract
Susceptibility and low frequency spontaneous polarization measurements have been made on TGFB. While our susceptibility data are in agreement with those recently reported by Mercado and Gonzalo, our spontaneous polarization values are considerably higher. These new data, in combination with the specific heat measurements of Strukov, Taraskin, and Kopstik, indicate that the calculations of Larkin and Khmel'nitskii provide a better description of the thermodynamic behavior of TGFB below Tc than docs classical Mean Field Theory.
