【摘要】 室温下测量了LiKSO₄单晶的旋光频散特性,用“晶体”旋光模型可以很好地拟合实验结果。在-180℃到680℃温度范围内,测量了LiKSO₄的旋光度,观测到四个相交:低温相变具有显著的温度迴线,相变温度随样品而异。讨论了上述相变模式与目前已报道的LiKSO₄相变资料之间的关系。更多还原

【Abstract】 Optical rotatory dispersion of LiKSO₄ crystal was pleasured at room temperature. The "crystal" nsodel of optical rotation fits well to the experimental results. In the temperature range from -180℃? to 680℃?, four phase transitions were observed by means of optical rotation measurement:Phase F3 Phase F2 Phase F₁ Phase X670℃→Phase α.The two transitions at low temperatures show obvious temperature hysteresis. All the transition temperatures are different from sample to sample. The relation between the transition sequence shown above and the data reported in literatures is discussed.更多还原
