Transition temperature in KDP type crystals under external pressures. Role of H-bond geometry
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 KH₂PO₄ family. We show that the universality of the transition temperature vs D-...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Резюме: | 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 KH₂PO₄
family. We show that the universality of the transition temperature vs D-
site distance dependence observed experimentally in some of the crystals
deformed by hydrostatic pressure is also obeyed by the other crystals of
the family as well as under the uniaxial pressure p = −σ₃. |
