在室温下对Cs_3H(SeO_4)_2的磁区结构进行了光学观察和X射线分析。在室温下，研究了外力对伴随磁区边界移动的组分离子重排的影响。在室温以上得到了各相晶胞之间的相互关系。当晶体通过TⅡ相变升温时，所有的氢键瞬间断裂，然后氢原子重新排列，在两个不同的相邻SeO4-2四面体之间形成新的氢键。当磁区边界移动时，SeO4-2四面体发生倾斜并移动到新的位置，同时氢键被破坏，然后新的氢键被重建。
Optical observation of domain structures and X-ray examinations of Cs 3 H(SeO 4 ) 2 were carried out above room temperature. The effect of an external force on the rearrangements of the constituent ions accompanied by the movement of domain boundary was studied at room temperature. The interrelations between unit cells in each phase were obtained above room temperature. When the crystal is warmed up through the phase transition at T II , all the hydrogen bonds are instantaneously broken, and then the hydrogen atoms are so rearranged as to form new hydrogen bonds between two diffrent adjacent SeO 4 -2 tetrahedra. When the domain boundary is moved, the SeO 4 -2 tetrahedra are tilted and displaced to new positions, and simultaneously hydrogen bonds are broken, and then new hydrogen bonds are reconstructed.
