Abstract
Antiferroelectric perovskites form an important family of functional electric materials, which have high potential in energy storage and conversion applications. However, a full understanding of their crystal structural formation is still lacking. PbZrO3-based materials can serve as a model system for investigation, not only because PbZrO3 was the first discovered antiferroelectric, but also because it undergoes a typical phase transition sequence from a high-temperature paraelectric to the low-temperature antiferroelectric phase, passing through a possible intermediate (IM) phase that is poorly understood. The IM phases usually exist only in a narrow temperature interval in pure PbZrO3, and therefore it is hard to capture them. On the other hand, with a small amount of Ti substitution, the Zr-rich PbZr1-xTixO3 (PZT, x 0.06) also displays a room-temperature antiferroelectric structure and goes through the same phase transition process as PbZrO3. In this case, the temperature range of the IM phase becomes wider, which makes a detailed study of the IM structures possible.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
