Dielectric dispersion and critical behavior in relaxor ferroelectric Pb(Mg1/3Nb2/3)O3–PbTiO3
Bibliographic record
Abstract
A critical behavior of dielectric susceptibility has been discovered in relaxor ferroelectric 0.75Pb(Mg1/3Nb2/3)O3–0.25PbTiO3. The real part of permittivity ε′ was found to follow the relation ε′−ε∞=χ′∝(T−T0)−2 at T>T0, and ε′∝(TC−T)−1 at T<TC, where T0≈TC<Tm; Tm is the temperature of the diffused ε′(T) maximum as is typical of relaxors; ε∞ is the frequency-independent parameter, and χ′ is the susceptibility depending on frequency via the “universal” relaxation law χ′∝fn−1. The susceptibility χ′ is suggested to originate from the polarization of polar nanoclusters.

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.
