A PREISACH ANALYSIS OF IRREVERSIBILITY IN A PARTICULATE THIN FILM: <font>Fe</font>-<font>Al</font><sub>2</sub><font>O</font><sub>3</sub>
Bibliographic record
Abstract
We present measurements of some of the principal response functions of a thin film of nanodimensional Fe particles embedded in A l 2 O 3 , specifically the temperature dependence of the moment measured under field cooled and zero field cooled conditions at temperatures between 5 K ≤ T ≤ 300 K in a low applied field h a =10 Oe , and the major hysteresis loop measured at T =5 K in applied fields between -2000 Oe ≤ h a ≤ + 2000 Oe . The data were analyzed within the framework of a generalized version of the Preisach model of hysteresis, which treats all magnetic systems as ensembles of interacting bistable Barkhausen elements, and which includes both thermal barrier relaxation effects and critical effects. Numerical simulations based on the model are able to replicate the principal structural features of the experimental data, and allow us to extract the characteristics of the bistable elements, specifically their moments μ, their coercive fields h c and their interaction fields h i .

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.
