Millimetre-wave ESR (electron-spin resonance) measurements of frustrated system ZnCr<sub>2<i>x</i></sub>Ga<sub>22<i>x</i></sub>O<sub>4</sub>
Bibliographic record
Abstract
The magnetic properties of a three-dimensional topological frustrated system ZnCr 2x Ga 2-2x O 4 , 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 Cr 3+ 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 T N . It turned out that the anti-ferromagnetic gap opens up just below T N 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 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.
