概要
- 論文の詳細を見る
Dielectric and thermal measurements were carried out for the RbH_2PO_4 crystal belonging to the tetragonal system at room temperature. The RbH_2PO_4 crystal, which could be obtained by heating the tetragonal RbH_2PO_4 crystal above the tetragonal-monoclinic transformation temperature, undergoes successive phase transitions at 390.1 K and 248.8 K. The tetragonal-monoclinic transformation is accompanied by a rearrangement of hydrogen bonds, namely, a change from a three-dimensional network of hydrogen bonds in tetragonal RbH_2PO_4 to a two-dimensional network in monoclinic one. The tetragonal space group I42d changes to the monoclinic P2_1/c by passing through the transformation temperature.
