“…These complexes form a network of elementary dipoles directed along the z-axis (figure 1). The dipole moments created in the paraelectric phase by the ( 14) and ( 12) (SO 4 ) complexes have the same direction which is opposite to the direction of the dipole moments created by the (11) and (13) complexes. Analogously, the dipole moments of the (25) and (26) type complexes are opposite to those of the (27) and (28) complexes.…”

“…This field is oppositely directed for the (11), (14) and (12) complexes.The phenomenological [10] and statistic [11][12][13][14][15] models of the phase transition in RHS-crystals, analogously to the Mitsui model for Rs, well describe the dielectric properties [16][17][18][19][20] and the Debye-type dynamic dielectric permittivity [12][13][14][15] in the mean field approximation. However, it is impossible to calculate the experimentally measurable dielectric permittivity of a mechanically free crystal, the piezoelectric coefficients, elastic constants and transverse dielectric permittivities using these models [12][13][14][15]. That is why the piezoelectric coupling to the strains should be taken into account [21].In this work we propose a modification of the four-sublattice model of the RbHSO 4 crystals, which takes into account the piezoelectric coupling to the strains ε i , ε j in the ferroelectric phase.…”

“…Для вибору оптимальних параметрiв теорiї необхiдно використовувати залежнiсть температури переходу T c вiд величини гiдростатичного тиску . На жаль, при x = 0 рiзнi автори наводять рiзнi значення для T c вiд 258 K до 265.1 K. Надалi ми будемо "прив'язуватись" до T c (0) = 265 K [8], оскiльки такою ж є температура ФП-кристала у працi [14], у якiй отримано залежностi значень T c (p).…”
