Abstract

fetched live from OpenAlex

Perovskite types Ba1 − xDy2x/3Ti0.75Zr0.25O3 (with x = 0.0, 0. 025, 0.05) ceramics have been prepared through solid state reaction route. The room temperature XRD study suggests that all the compositions have single phase cubic symmetry with space group Pm-3m. Temperature dependent dielectric studies of the ceramics have been investigated in the frequency range from 50 Hz to 1 MHz. The densities of the samples are determined using Archemedes' principle and found to be ∼ 98% of x-ray density. The dielectric study revealed diffuse phase transition of second order. A broad dielectric anomaly coupled with the shift of dielectric maxima toward a higher temperature with increasing frequency indicates the relaxor-type behavior in the ceramics. There is drastic reduction in dielectric loss is observed. The diffusivity increases with increase in Dy contents in the studied composition range. The transition temperature decreases with increase in Dy contents due to the decrease in grain size.

Full frame distilled prediction

Teacher imitation

Not 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.
