• 論文の詳細を見る

• A study of phase transition of ice Ic is made by Takagi's method, where twentyfive order parameters and a unit cell comprising eight molecules are used andenergies of interaction between molecules are considered. The free energy isminimized with respect to these parameters by the simplex method. When the?nteractuon-energy parameter is positive, the ordered phase is ferroelectric and aminjmunt ttnit cell has two molecules. When it is negative, the ordered phase isantiferroelectric and a minimum unit cell has four molecules. In this phase, thed?rection of dipoles on one sublattice of the diamond structure is normal to that ofthe dipoles on the other sublattice.
