Infrared and Raman spectra of lithium ammonium tartrate monohydrate were obtained in the frequency region at temperatures of 15 - 300 K. No soft phonon mode was observed, so the ferroelastic and ferroelectric phase transition at is of order - disorde

A substantial hardening of the phonon modes near 75 and 90 cm−1 with hydrostatic pressure was observed in the far-infrared spectra of Rochelle salt, but no influence of pressure on the soft mode near 20 cm−1 was found. A large increase in the fer

A substantial increase of the ferroelectric phase transition temperature with hydrostatic pressure was observed for lithium thallium tartrate monohydrate single crystals. The temperature dependence of the permittivity shows an unusual shape exhibitin

Single crystals of 2-cyclooctylamino-5-nitropyridine (COANP) and 2-(N-(L)-prolinol-5-nitropyridine (PNP) were grown from tetramethoxysilane gels. Lowering the temperature or seeding of supersaturated water/ethanol gel solutions led to optical quality

Dierectric properties of A2BX4 type ferroelectrics in the incommensurate phase can be controlled by using external stresses (electrical or mechanical). In all A2BX4 type ferroelectrics, the stress components σzz or σxx either do not shift the trans
