17. For a comparison with our results we have tried to reproduce the calculations of Ref. 7 with the same set of material parameters and we were not able to obtain the same results. However, we have found that the difference in the mean-field free energies of the S and C structures contributes 40 times more to the critical field than the polarization fluctuations. Therefore we conclude that the transition between the S and C structures is governed mostly by the mean-field mechanisms.
