- 論文の詳細を見る
Dielectric, thermal and X-ray diffraction measurements are performed for(NH.).ZnCI.. Ferroelectric activity is confirmed below 270 K and two otherphase transitions are found at 319 K and 406 K. Phase I (7'>406 K) is the normalphase. Phase II (319< T< 406 K) and Phase III (270< T< 319 K) are paraelectricand antiferroe[ectric, respectively, with c=4c, where c(, is a unit ce[[ parameterof the normal phase. Phase IV (7'< 270 K) is the ferroelectric phase havingc=3c(,.
