High-resolution neutron study of the effects of magnetic dilution in the strongly frustrated system SrCr<sub><i>x</i></sub>Ga<sub>12<i>x</i></sub>O<sub>19</sub>
Bibliographic record
Abstract
We have pursued the neutron examination of SrCrxGa12xO19, with special emphasis on the role of magnetic dilution in the spin dynamics and freezing. We have examined samples with different levels of magnetic dilution, ranging from 7.0 < x < 8.8, characterized by neutron powder diffraction with Rietveld refinements and bulk susceptibility. The elastic magnetic response examined by high-resolution neutron scattering (µeV range) has confirmed the trend on increasing dilution: the decrease of the freezing temperature as well as of the frozen moment/magnetic site. However, the least diluted sample that we have produced with x = 8.8, deviates from this trend, with a smaller than expected freezing temperature and frozen moment. This suggests that the freezing might be suppressed at the clean limit. PACS Nos.: 75.10Nr, 75.25+z, 75.40Cx, 75.40Gb

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.
