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 sequences of the phase transitions in Cs2CdI4 and Cs2ZnI4 were investigated with the help of the NQR, NMR and X-ray methods. The dielectric and second harmonic generation measurements were used as complementary techniques. Incommensurate phases were found in both substan...

摘要:The sequence of phase transitions in Cs2ZnI4 was studied by several methods. The incommensurate one-dimensional modulation with the wave vector qΔ = (1/2 + Δ)a* was revealed in the interval between 120-108 K. The nature of incommensurate and lock-in transitions are discussed...

摘要:The orientational order of monomerically thin films of polydimethylsiloxane melt deposited on the surfaces of cylindrical pores is investigated in this paper by solid-state deuterium nuclear magnetic resonance. Spectra demonstrate substantial orientation of the methyl groups by t...
