Orientation‐dependent electrical property and domain configuration of Mn‐doped Pb(In <sub>0.5</sub> Nb <sub>0.5</sub> )O <sub>3</sub> –PbTiO <sub>3</sub> single crystal
Bibliographic record
Abstract
Abstract Orientation dependence of electrical properties and domain configurations of 8 mol% Mn‐doped rhombohedral PIN ‐ PT (0.68Pb(In 0.5 Nb 0.5 )O 3 –0.32Pb(Ti 0.92 Mn 0.08 )O 3 ) rhombohedral single crystals were investigated with an emphasis on studying the variations of coercive field ( E C ), internal field ( E i ) on domain patterns. Our results showed that for both [001] and [110]‐oriented samples, the coercive field and internal field decreased with temperature ( T ) increasing in rhombohedral phase, and a peak appeared above rhombohedral‐tetragonal phase transition temperature ( T RT ). The abnormal peaks between T RT and Curie temperature on E C ‐ T and E i ‐ T plots are explained by taking into consideration the ferroelectric phase transition and variation of defect polarization, which provides assistant comprehension on the dynamic of defect dipoles during phase transition at high temperature. Bubble‐ and ribbon‐like domain patterns were observed in (001)‐ and (110)‐plane, respectively, and smaller value of short‐length correlation radius in (001)‐ plane indicates less aggregation of polar nanoregions in this crystallographic plane than that in (110)‐plane.

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.
