Effect of chemically ordered regions on the acoustic behaviors in Pb(Mg1/3Nb2/3)O3 studied by Brillouin scattering
Bibliographic record
Abstract
The longitudinal acoustic phonon modes of Pb(Mg1/3Nb2/3)O3 (PMN) and La-doped PMN were investigated by using Brillouin spectroscopy and compared. The acoustic behaviors of La-doped PMN were very similar to those of pure PMN in spite of its much larger size of the chemically ordered regions induced by La-doping. The relaxation times of La-doped PMN in the ergodic relaxor phase were almost the same to those of PMN. This result shows that the temperature evolution of dynamic polar nanoregions and the related high-frequency dynamics of PMN-based crystals in the gigahertz range are not affected by the size of the B-site cation-ordered regions.

How this classification was reachedexpand
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.
