摘要：

Measurements of layer compression modulus B have been performed on the chiral smectic liquid crystals showing V-shaped switching to study elastic properties. The temperature dependence of B in binary mixtures shows the usual cusp-like behavior at the untilted-tilted smectic phase transition in contrast to that in a three-component mixture showing V-shaped switching [Shibahara et al.: Phys. Rev. E 63 (2001) 051707]. Moreover, we observed the abrupt softening of B in the close vicinity of the tilted-tilted smectic phase transition (ferrielectric-antiferroelectric phase transition) for the first time.
