Giant magneto-optical Faraday effect in GaP epilayers containing MnP magnetic nanoclusters
Bibliographic record
Abstract
We report a giant magneto-optical (MO) effect in a GaP(011) epilayer with embedded MnP nanoclusters (GaP:MnP) grown on a GaP(011) substrate using metal-organic vapor phase epitaxy. The MO effect exhibits a hysteretic behavior when sweeping the applied magnetic field, thereby indicating a clear dependence upon the magnetization of the sample. The measured Faraday rotation per unit length is 60 times higher in the epilayer than that of GaP at room temperature. The role of the magnetization in the MO effect makes it possible to increase this factor even further by lowering the temperature well below the Curie point (TC) of 292 K for those samples. We observed an increase of the Faraday rotation at longer wavelengths, indicating that those GaP:MnP epilayers could potentially be useful for enhanced MO effects in the visible and infrared regions of the electromagnetic spectrum.

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.
