Unusual behaviour of binary mixtures of ferroelectric and antiferroelectric liquid crystals with three chiral centres.
Two binary mixtures have been studied of homologies from a series derived from 4-alkoxybiphenyl-4'-carboxylic acid with three chiral centres exhibiting ferroelectric , antiferroelectric and tilted hexatic phases. one homologue exhib...

Ferroelectricity in antiferroelectric NaNbO3 crystal
Sodium niobate (NaNbO3, or NNO) is known to be antiferroelectric at temperatures between 45 and 753 K. We show experimentally the presence of the ferroelectric-seeded solution growth. The ferroelectric phase and new phase t...

Phase transition hysteresis at the antiferroelectric-ferroelectric boundary in PbZr1-xTixO3
PbZr1−xTixO3 exhibits an antiferroelectric-ferroelectric phase boundary at the composition x ∼ 0.06. In this work, we have carried out systematic structural investigations of single crystals and ceramics with several compositions ac...
