Bibliographic record
Abstract
The magnetic properties of a three-dimensional topological frustrated system ZnCr2xGa2-2xO4, which is an anti-ferromagnet with a spinel structure, have been investigated by our millimetre-wave ESR (electron-spin resonance) measurements using the pulsed magnetic field up to 16 T in the temperature region from 1.8 to 265 K. In the high-temperature region, typical Cr3+ EPR (electron-paramagnetic resonance) with the g-value of 1.95 was observed. For the x = 1 sample, AFMR (anti-ferromagnetic resonance) with the easy-plane-type magnetic anisotropy was observed below TN. It turned out that the anti-ferromagnetic gap opens up just below TN suggesting that the transition is of the first order. The x dependences of ESR were also observed and their temperature dependences of the g-value and the linewidth will be discussed in connection with those of other frustrated systems such as Kagome lattice substance.

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.
