A comparative analysis of Raman spectra of barium titanate in various forms is performed over a broad range of temperatures (from 80 to 400 K). In particular, the evolution of A₁(2TO) and E(1TO) soft‐mode components, sensitive to strain, is monitored for such materials as single crystal, ceramic, and polycrystalline film. Based on the temperature dependence of these components, a sequence of phase transitions is established for each of the aforementioned forms.

钛酸钡的晶格动力学：单晶，陶瓷和多晶膜

在很宽的温度范围（80至400 K）内进行了各种形式的钛酸钡拉曼光谱的比较分析。特别是，对于诸如单晶，陶瓷和多晶膜之类的材料，对应变敏感的A ₁（2TO）和E（1TO）软模组件的演变受到监控。基于这些成分的温度依赖性，为上述每种形式建立一系列相变序列。
