The tricritical phase transition of ferroelectric triglycine selenate (TGSe) has been investigated under the influence of weak uniaxial stress and electric fields by means of a high sensitive calorimetric technique. The effect of deuteration on the l

The phase transition in a 90% deuterated sample of TGSe has been investigated by calorimetric and dielectric measurements. As a consequence of the presence of an internal crack in the sample, the transition takes place in two stages separated by an i
