摘要:Abstract(#br)The refractive index dispersion of the γ-BiB 3 O 6 crystal in the wavelength range 0.43–0.81 μm has been measured. It has been shown that the principal refractive indices n 1 , n 2 , and n 3 are on average higher than those of α-BiB 3 O 6 , but are slightly...

摘要:Phase transition (PT) was found in Cs3Bi2I9 single crystal at T0=223 K. Optical birefringence, dielectric and elastic constants and differential scanning calorimetry have been studied. It was found that birefringence Δnc, and twinning picture appeared on (001) — and (10...

摘要:Crystals A2BX4 become of great interest for investigators because they have an incommensurate phase in a certain temperature range. Since modulation wave period is still much shorter than wavelength of the visible light, there is opinion that macroscopic methods (such as met...

摘要:In this paper the results of birefringence studies and of optical observations in polarized light in a wide temperature region are presented for crystals Cs2CdI4 and Cs2ZnI4. There is the following sequence of phases: commensurate orthorhombic Pnma ↔ incommensurate ↔ monocli...

摘要:The successive symmetry changes at phase transitions in crystals CLM, CLW, RLM, RLW (see text) were studied by analysing the configurations of twin boundaries and arrangement of optic indicatrices of twins, as well as using the data of other experiments. The caesium-containi...

摘要:(T - x) phase diagram has been investigated by polarizing optic and birefringence methods, differential scanning calorimetry and X-ray study. A small amount of rubidium in CsLiSO4 as well as cesium in RbLiSO4 reduces the temperature of transition into ferroelastic phase P112...

摘要:The crystals of Rb2NaDyF6 and Rb2KDyF6 were grown and the optic, thermal and X-ray investigations were made in temperature range 80-450 K. The structural phase transitions were observed in both crystals. But the character of these trams-formations and the distortion type are diff...
