We have carried out a spectroscopic study on a prototype ferroelectric nematic material (RM734) doped with a non-polar chiral compound. The mixture presents two chiral nematic phases, one conventional (N*) and the other polar (NF*), whose behaviours

Materials that exhibit high nonlinear optical (NLO) susceptibilities are considered as promising candidates for a wide range of photonic and electronic applications. Here, we argue that the ferroelectric nematic (NF) materials have sufficient potenti

The second-order susceptibility tensor of three liquid crystals composed of banana-shaped molecules has been fully determined. The measurements were carried out in single domain samples, aligned by means of an electric field parallel to the cell surf

The birefringence and optical activity of Rb2ZnCl4 have been measured in the normal, incommensurate and ferroelectric phases. The measurements have been carried out using a high-accuracy universal polarimeter (HAUP). In contrast to previous observati

Triglycine fluoroberyllate (TGFB) undergoes a phase transition at 73°C from a paraelectric high-temperature phase (space group P21/m) to a ferroelecmc phase (space group P21). The optical activity, rotation of the optical indicatrix and birefringenc

We report structural results that evidence the polarization distribution of the blocks in the columnar phase of an achiral bent-core liquid crystal. The study was performed using resonant x-ray diffraction at the sulfur K edge on oriented samples ali

Thermal hysteresis and memory effects near the lock-in transition of [N(CH 3 ) 4 ] 2 ZnCl 4 are investigated by means of dielectric susceptibility measurements. The general kinetic behaviour of this material differs considerably from the one observed

A phenomenological model for the dielectric anomaly at the incommensurate-ferroelectric phase transition in [N(CH3)4]2XCl4 (X=Co, Zn) is presented. A first order transition between the incommensurate phase (in a sinusoidal regime) and the ferroelectr

A structural investigation of the compound 8-OPIMB-NO2 is carried out. This material is a mesogen formed by bent-core molecules where the so-called B7 phase was originally proposed. X-ray data are successfully indexed in terms of a oblique two-dimens
