- 論文の詳細を見る
Observation of CH<SUB>3</SUB>NH<SUB>3</SUB>I crystal under a polarizing microscope showed a rectangular domain structure in the δ phase. Dielectric measurement revealed an antiferroelectric behavior of the same phase. These results indicate that the δ phase has orthorhombic or monoclinic structure with C–N axes of CH<SUB>3</SUB>NH<SUB>3</SUB><SUP>+</SUP> ions inclining along its a or b axis in an antiferroelectric way.
