Spontaneous helix formation in polar smectic phase
Ewa Gorecka, Magdalena Majewska, Ladislav Fekete +4
In soft ferroelectric crystals, the depolarization field can be reduced by periodic distortion of the polarization direction. In the polar nematic and tilted smectic phases, this p…

To be or not to be polar: the ferroelectric and antiferroelectric nematic phases
Ewan Cruickshank, Paulina Rybak, Magdalena Majewska +8
We report the properties of two new series of compounds that show the ferroelectric nematic phase in which the length of a terminal chain is varied. The longer the terminal chain,…

Multiple polar and non-polar nematic phases
S. Brown, E. Cruickshank, J. M. D. Storey +5
Liquid crystal materials exhibiting up to three nematic phases are reported. Dielectric response measurements show that while the lower temperature nematic phase has ferroelectric…
