                      under compression, the second-order phase transition line is
                      observed down to the tricritical point as the transition
                      temperature decreases to 250 K. A tricriticality at a
                      similar temperature is also revealed in the mixed crystals
                      on Sinline imageSe substitution. For the mixed crystals with
                      Sninline imagePb substitution, ultrasound, hypersound, and
                      low-frequency dielectric studies also show heterophase
                      features appearing on decrease of the ferroelectric
                      transition temperature below a so-called “waterline
                      temperature” near 250 K. Such behavior agrees with the
                      Blume–Emery–Griffiths (BEG) model appropriate for the
                      ferroelectric system under investigation with a three-well
                      local potential for the order parameter fluctuations. The
                      BEG model modified by the random-field phase diagram in the
                      vicinity of the tricritical point qualitatively explains the
                      influence of the cationic substitution on the (Pbinline
