Abstract
We show that the magnetism of Fe/Cu nanostructured thin films can be controlled by adjusting an interfacial FeCu alloy formed during in situ ion-beam bombardment of the Fe atoms, promoting intermixing between the Fe and Cu, forming an FeCu alloy. This intermixing results in prominent changes to the inter- and intracrystallite interactions which govern the magnetism. With increased interfacial alloy content, the films were modified from a multilayer to a dispersion morphology. This control over increased disorder tuned the magnetic interactions, such as enabling the coexistence of superparamagnetism of Fe nanocrystallites and magnetic ordering of the FeCu component so that a film’s coercivity increased with warming near TC.

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 it
