摘要：

In this paper, we shall present a simple irreversible rotation model with a couple of polarization vectors to account for the hysteretic phenomena in SmC(A)* phases. From a numerical calculation, a double hysteresis curve was found in antiferroelectric SmC(A)* phase, whereas a single curve was found in the ferroelectric SmC* phase. Remarkably it is found that there exists a direct ferroelectric-ferroelectric transition under a sinusoidal electric field with a sufficiently large amplitude and high frequency in qualitative agreement with experimental findings.
