Abstract
X-ray diffraction studies on a $\mathrm{Pb}({\mathrm{Zn}}_{1∕3}{\mathrm{Nb}}_{2∕3}){\mathrm{O}}_{3}$ (PZN) single-crystal sample show the presence of two different structures. An outer layer exists in the outer most $\ensuremath{\sim}10$ to $50\phantom{\rule{0.3em}{0ex}}\ensuremath{\mu}\mathrm{m}$ of the crystal, and undergoes a structural phase transition at the Curie temperature ${T}_{C}\ensuremath{\approx}410\phantom{\rule{0.3em}{0ex}}\mathrm{K}$. The inside phase is, however, very different. The lattice inside the crystal maintains a cubic unit cell, while ferroelectric polarization develops below ${T}_{C}$. The lattice parameter of the cubic unit cell remains virtually a constant, i.e., much less variations compared to that of a typical relaxor ferroelectric, in a wide temperature range of 15 to $750\phantom{\rule{0.3em}{0ex}}\mathrm{K}$. On the other hand, broadening of Bragg peaks and change of Bragg profile line shapes in both longitudinal and transverse directions at ${T}_{C}$ clearly indicate a structural phase transition occurring.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; both teacher heads agree on what is shown here.
