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 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 it
