Bibliographic record
Abstract
Ceramics of a new solid solution, (1 − x)Pb(Mg1/3Nb2/3)O3-xBi(Zn1/2Ti1/2)O3 [(1-x)PMN-xBZT], have been prepared (with x = 0.05–0.30) and investigated for their structure and relaxor ferroelectric properties. The structure remains pseudocubic (or rhombohedral) up to the solubility limit of x = 0.275. All the compositions studied show broad and diffuse peaks in the temperature and frequency dependences of dielectric permittivity, indicating typical relaxor behavior. The temperature dependences of dielectric permittivity for all the samples studied follow an empirical quadratic law that describes the high temperature slope of the permittivity. The diffuseness in the dielectric peaks was found to increase linearly with the increasing amount of BZT, which can be attributed to the increase in chemical disorder in the system.

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.
