Growth and characterization of relaxor ferroelectric (1-x)Pb(Sc/sub 1/2/Nb/sub 1/2/)O/sub 3/ - xPbTiO/sub 3/ single crystals
Bibliographic record
Abstract
Growth and characterization of the single crystals of complex perovskite (1-x)Pb(Sc/sub 1/2/Nb/sub 1/2/)O/sub 3/-xPbTiO/sub 3/ [PSNT] with composition near the MPB (x=0.425) are reported in this paper. The PSNT crystals were grown by high temperature solution method using the (PbO + /spl delta/B/sub 2/O/sub 3/) system as flux. By analyzing the defects and morphology of the as-grown crystals, we have optimized the growth parameters and the flux system, leading to a significant improvement in the quality of crystal grown. Domain observation by polarized light microscopy reveals that the structure of the PSNT57.5/42.5 crystal has very complex symmetry at room temperature. The PSNT crystals have been characterized by means of the X-ray, dielectric and ferroelectric measurements.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
