Abstract
Phase diagram of the ANNNI model with the third neighbour interaction is obtained to clarify the ferrielectric phases appearing in the seque nces of phase transitions of certain ferroelectric smectic liquid crys tals. While various mesophases are ferrielectric, those with wave numb er q = 3/8 and 3/10 come out to exhibit the second order phase transit ion from antiferroelectric phase to ferrielectric one with decreasing temperature. The phases with q = 4/13 and 4/11 are the candidates for the ferrielectric phases FIH and FIL observed just above and below the SmCgamma, respectively.
