Freedericksz transition of nematics in an oblique magnetic field
نویسندگان
چکیده
2014 A planar nematic layer will show a Freedericksz transition in a magnetic field perpendicular to the unperturbed alignment. This transition occurs at H = Hc1 (splay) in a perpendicular field and at H = Hc2 (twist) in a field parallel to the layer. If the magnetic field is applied at an oblique angle with respect to the layer, but perpendicular to the direction of alignment, the threshold field can be varied continuously between Hc1 and Hc2. We calculate the deformation pattern above the threshold and compare our results with experiments on MBBA. LE JOURNAL DE PHYSIQUE TOME 36, JUILLET-AOÛT 1975, Classification Physics Abstracts 7.130

Freedericksz Transition of a Homeotropic Nematic Liquid Crystal in Rotating Magnetic Fields
— We present experimental and theoretical investigations on the Freedericksz transition of a homeotropic nematic slab in rotating magnetic field. Two characteristic fields, and one critical frequency are necessary to describe the behaviour of the sample : — .ffa() ...
متن کاملNonequilibrium Phenomena in Liquid Crystals
The briefest glance through the literature on nonequilibrium phenomena shows that complex fluids, particularly liquid crystals, are often favored for experimental investigations. This might seem surprising in that complex fluids, as befits their name, are difficult materials: experiments require subtle tricks to prepare reproducible samples; theoretical descriptions lead to notoriously messy eq...
متن کاملAnisotropy induced director refraction inside inversion walls in nematic liquid crystals
2014 We compute the texture of the inversion walls which appear in nematics in a magnetic field. In the isotropic case, where the 3 curvature elastic constants are equal, the Brochard planar description is correct. In the anisotropic general case, we find an unpredicted director rotation around the field, which minimizes the elastic free energy of the wall, by transferring some curvature distor...
متن کاملElectro-optical effect of a magnetically biased ferronematic liquid crystal.
The electro-optical effect of a magnetically biased ferronematic liquid-crystal film is investigated by using birefringence measurements. When a magnetic field is applied, the threshold voltage of the Freedericksz transition no longer exists. The dependence of the birefringence on the magnetic field strength in the low field regime is presented. A theory that accounts for the results is given.
متن کاملAbnormal Rolls in Hybrid
We report experimental and theoretical results on the conductive regime of electroconvection in hybrid aligned nematics. The drifting oblique/normal rolls below/above the Lifshitz frequency are observed at the onset of electroconvection under a.c. voltage. The experimental data on the threshold voltage, wavelength, oblique angle and drift period of the rolls as function of a.c. frequency are in...
