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