Photoinduced nonlinear magnetoelectric effect detection in Zn2Y hexaferrite
Bibliographic record
Abstract
The photoinduced nonlinear magnetoelectric effect was investigated in the single-crystal Y-type Ba2Zn2Fe12O22 (Zn2Y) hexaferrite under ultraviolet radiation. We observed a downshift of the ferromagnetic resonance frequency caused by decreasing the effective saturation magnetization. The maximum observed shift of the resonance frequency was equal to 110 MHz corresponding to effective saturation magnetization decrease by 256 G. A strong nonlinear change in effective saturation magnetization was observed as the result of the photoinduced nonlinear magnetoelectric effect. The strength of the photoinduced nonlinear magnetoelectric effect was found to be up to 85% higher compared to the strength of the nonlinear magnetoelectric effect. The results demonstrate the possibility of optical tuning of the ferromagnetic resonance frequency and the mechanism of using the single-crystal Zn2Y for radiation detection.

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.
