Within the model proposed earlier, we study the effect of hydrostatic pressure on relaxational dynamics of deuterated KD 2 PO 4 type ferroelectrics. Within the four particle approximation for deuteron ordering model and using the Glauber approach, we calculate the longitudinal dynamic dielectric permittivity of the strained crystal. Possible pressure dependences of the permittivity and relaxation times are discussed.
