The generalized mean-filed theory by Dumorngrattana and Huang, in which higher order terms are introduced into the free energy expression, succeeded to explain the anomalous change in Ps/ θ of DOBAMBC at the A-C* phase transition. Generally speaking, it should be around the tri-critical point that the higher order terms are important. In the present study, the temperature dependence of Ps/ θ of several ferroelectric liquid crystals was investigated in detail.
