Paper Abstract

The temperature-concentration dependence of the field hysteresis loop ((delta) U) in nematic- cholesteric mixtures was researched. The matrices were the mixtures of cianobipheniles in which helical structure was created by the addition of optically active dopants (0.4 ... 2.5 weight%) or addition of non-liquid crystal material BIXH-3. It was shown that the magnitude of (delta) U decreases with the increasing of a temperature. The maximum of the (delta) U can be attained by the change of the concentration of the dopant in mixtures.
