Abnormal dielectric behavior and domain reorientations in the (Bi0.5Na0.5)0.92Ba0.08TiO3 ceramic below the critical temperatures
Bibliographic record
Abstract
(Bi[Formula: see text]Na[Formula: see text])[Formula: see text]Ba[Formula: see text]TiO 3 lead-free ceramic material was synthesized via the conventional solid-state reaction method. The dielectric and ferroelectric behavior was analyzed below the previous reported depolarization temperature, [Formula: see text]. The structural characteristics through the Raman spectroscopy were studied in the same temperature range. The dielectric analysis has shown a complex behavior characterized by an anomalous region between 50°C and 70°C, distinct from the primary ferroelectric and antiferroelectric transitions. This anomaly has been attributed to a combination of factors, including changes in domain reorientation and switching due to the increasing electrical stabilization of the antiferroelectric phase, which is confirmed by variations in remnant polarization, recovered energy density, and efficiency. The results have suggested that the material’s performance can be tailored by operating within this specific temperature range, opening up interesting possibilities for energy storage and other applications where control over the switching between ferroelectric and antiferroelectric phases is crucial.

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; a candidate call from one teacher head, not a consensus.
