We propose a modification of the two-sublattice Mitsui model that takes into account a coupling with diagonal components of the strain tensor. Within the developed model, we calculate the piezoelectric and elastic ...

Within the four-particle cluster approximation for the proton ordering model, we study effects of external pressures which do not lower the symmetry of crystals on deuterated ferroelectrics and antiferroelectrics of ...
