Such an effect would lead close to the nematic phase to an increase of the layer thickness, and the inversion point for the expansion coefficient variation would

correlation lengths will result in a larger integrated intensity, thus giving rise to smaller values for the susceptibility «. These effects are strongest close to the phase

In a simple model we show that concentration fluctuations need not be accompanied by order parameter fluctuations and that the range of instability, the critical wave length and

depends on what kind of fluctuations are present in the smectic A phase : layer undulations or molecular tilt. They could of course, in general, occur

Precise measurements of the Kerr effect [6, 9] and magnetic birefringence [6, 7] in the isotropic phase of. some nematic substances have been

The crucial argument for an isotropic formation mechanism of the longitudinal or pre-chevron domains in the case of homogeneous orientation, and the (( Maltese

- The measurement of X-Ray diffuse scattering from HAB was carefully carried out above the smectic C-nematic phase transition temperature T, and it is found
