Abstract
The microstructure and phase transition in relaxor ferroelectric $\mathrm{Pb}({\mathrm{Mg}}_{1/3}{\mathrm{Nb}}_{2/3}){\mathrm{O}}_{3}$ (PMN) and its solid solution with ${\mathrm{PbTiO}}_{3}$ (PT), $\mathrm{PMN}\ensuremath{-}x\mathrm{PT},$ remain to be some of the most puzzling issues of solid-state science. In the present work we have investigated the evolution of the phase symmetry in $\mathrm{PMN}\ensuremath{-}x\mathrm{PT}$ ceramics as a function of temperature $(20<T<500\mathrm{K})$ and composition $(0<~x<~0.15)$ by means of high-resolution synchrotron x-ray diffraction. Structural analysis based on the experimental data reveals that the substitution of ${\mathrm{Ti}}^{4+}$ for the complex B-site $({\mathrm{Mg}}_{1/3}{\mathrm{Nb}}_{2/3}{)}^{4+}$ ions results in the development of a clean rhombohedral phase at a PT concentration as low as 5%. The results provide insight into the development of ferroelectric order in PMN-PT, which has been discussed in light of the kinetics of polar nanoregions and the physical models of the relaxor ferroelectrics to illustrate the structural evolution from a relaxor to a ferroelectric state.

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
