Properties of system with induced SmCA* phase

Physical macroscopic properties such as the spontaneous polarization P-S, t he tilt angle theta, dielectric permittivity epsilon (perpendicular to) as a function of temperature were measured for system with induced SMCA* compo sed simultaneously of three ring chiral esters with partially fluorinated t erminal chain and nonfluorinated. Dielectric and spontaneous polarization m easurements on heating and cooling runs show a thermal hysteresis for the p hase transition between SmC* and SMCA* phases.
