Critical exponents of the order parameter of diffuse ferroelectric phase transitions in the solid solutions based on lead germanate: studies of optical rotation
D. I. Adamenko, R. O. Vlokh
In this work we show that the critical exponents of the order parameter (CEOPs) of diffuse ferroelectric phase transitions (DFEPTs) occurring in lead germanate-based crystals can b…
Critical Behavior of Sn2P2S6 and Sn2P2(Se0.28S0.72)6 Crystals under High Hydrostatic Pressures
B. Zapeka, M. Kostyrko, I. Martynyuk-Lototska +1
Basing on the temperature dependences of optical birefringence for Sn2P2S6 and Sn2P2(Se0.28S0.72)6 crystals subjected to hydrostatic pressures, we prove unambiguously that Sn2P2S6…
Once More About the "Forbidden" Domain Structure and the Isolated Point in K2Cd2xMn2(1-x)(SO4)3 Langbeinites
R. Vlokh, I. Girnyk, O. V. Vlokh +3
The domain structure in K2Cd2xMn2(1-x)(SO4)3 (x=0.5, 0.7 and 0.9) langbeinite crystals is studied with the aid of optical polarization microscopy. It is shown that the domain walls…
Phase Coexistence in Cs3Bi2I9 Ferroelastics: Optical, Dilatation and Ultrasonic Velocity Studies
I. Girnyk, O. Krupych, I. Martunyuk-Lototska +2
The results for dilatometric, ultrasonic velocity and the domain struct-ure studies of Cs3Bi2I9 crystals in the course of ferroelastic phase trans-ition are presented. It is shown…
Electrically and magnetically induced optical rotation in Pb5Ge3O11:Cr crystals at the phase transition. 2. Faraday effect in pure and Cr-doped lead germanate in the presence of electric field and spontaneous polarization
D. Adamenko, I. Klymiv, V. M. Duda +2
This work presents the results for the Faraday rotation in pure and Cr-doped lead germanate crystals studied in the course of proper ferroelectric phase transition. We show that th…
