摘要

摘要 研究了 Sr2Ta2O7 陶瓷结构相变中低频拉曼散射的温度和压力相关性。拉曼光谱是在 0 至 -185°C 的温度范围内测量的。在 T = -110°C 时,B1g 对称的一个低洼模式的拉曼位移与温度有关。Sr2Ta2O7 的这种反常现象与铁电相变有关。在冷却过程中,B1g 模式的峰宽在 150°C 时发生变化,B3g 和 B1g 模式的拉曼位移随温度的变化也变得异常。在高压下,我们发现了 4 至 5.5 GPa 之间的相变。角度色散 X 射线衍射数据表明,相变是从不相称到相称态。

Effect of Temperature and Pressure on Low-Frequency Raman Scattering from Strontium Tantalate Ceramic Material

The temperature and pressure dependences of low-frequency Raman scattering were studied on structural phase transformations of Sr2Ta2O7 ceramics. The Raman spectrum was measured over a temperature range from 0 to –185°C. The temperature dependence of the Raman shift of a low-lying mode of the B1g symmetry shows at T = –110°C. This anomaly of Sr2Ta2O7 is related to a ferroelectric phase transition. During cooling, the peak width of the B1g mode shows a change at 150°C, and the temperature dependence of Raman shifts of B3g, and B1g modes becomes abnormal. Under high pressure, we discovered a phase transition between 4 and 5.5 GPa. Angle-dispersive X-ray diffraction data suggest the phase transition from incommensurate to commensurate states.
