Reflection-specific r matrices between uhkl(r) for different temperatures. The difference in r values corresponds to structural evolution. The (002) reflection for crystal A shows an abrupt r change after 410°C, suggesting the abrupt removal of most defects. This is less evident in the reflection for crystal B, which shows many subtle structural changes as a function of temperature. The red dashed lines indicate where the temperature sampling changed. Black arrows represent the most noticeable changes in displacement. |
