Depolarization Effect of Magneto-Optic Crystal GdYBiIG in Adjustable Magnetic Field
Bibliographic record
Abstract
The optical system has been established in which the changes of polarization state for magneto optic crystal can be measured. In this optical system, WGY model semiconductor laser is applied as the light source, and the tuning range of the intensity of magnetic field is 0～1500 mT. Depolarization effect in GdYBiIG crystal which often be used in optical isolator is measured in large variation range of adjustable magnetic field. The experiment result shows that polarization performance will be best in GdYBiIG crystal when it reaches saturated magnetization. And the depolarization effect occurs when the intensity of magnetic field increases over saturation intensity. The principle for magnetic depolarization effect is also given according to the experimental result. It presents that magnetic circle dichroism and magnetic linear birefringence are the reasons which cause depolarization effect. From these results, it is optimum to make sure that the magnetic field should be lager only a little than the saturation intensity of magnetic field.

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.
