Relation of domain properties to structural changes in perpendicularly magnetized ultrathin films
Bibliographic record
Abstract
The influence of interface mixing upon the magnetic domain properties in perpendicularly magnetized ultrathin films has been studied using Fe/2 ML Ni/W(110) samples. Annealing of films with an Fe thickness of 1--1.5 ML produces interface mixing that can be quantified using Auger electron spectroscopy, and related to the changes in domain properties (such as the activation energy for domain wall pinning, the domain correlation length, and domain concentration) as measured by the low frequency ac magnetic susceptibility. Analysis of the susceptibility, as well as model calculations of the magnetic anisotropy, suggest that pinning is caused by the perturbation of the domain wall energy by monolayer steps in thickness. Initially, annealing smooths the film, thus increasing the domain correlation length and activation energy. Further annealing causes mixing at the Fe/Ni interface, which reduces the anisotropy, thus reducing the activation energy and increasing the domain concentration. Annealing above 550 K breaks up the film and there is no magnetic response in the measurable temperature range.

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; both teacher heads agree on what is shown here.
