Abstract
The vanishing of the ferroelectricity at 0°K and high pressure has been investigated in displacive (K1-χNaχTaO3 and SbSI) and hydrogen-bonded (KDP-type) ferroelectrics. The manner in which T c → 0°K is markedly different in the two classes emphasizing the basic differences in the mechanisms for their transitions. Comparisons between the results on deuterated and non-deuterated KDP-type crystals reveal differences pertaining to the importance of tunneling.Keywords
