The intermixing induced perpendicular magnetic anisotropy in ultrathin Co/Pt multilayers
Bibliographic record
Abstract
It has been observed that a perpendicular interface contribution to the magnetic anisotropy can rotate the easy magnetization direction from within the film plane to perpendicular to the film plane when the Co thickness in Co/Pt multilayers is below a critical value that is in the range of (sub)nanometers. In this work, mixed CoPt phases mainly consisting of disordered fcc CoPt were found to be responsible for the perpendicular magnetic anisotropy (PMA) for the film deposition end-Hall voltage equal to 140 V. Estimates of mechanisms that could be responsible for the PMA such as “orange peel” coupling, exchange bias, and magnetostriction indicate that they are too weak. We believe that this PMA is driven by the heat of mixing and relatively higher interfacial energy since the Co layer thickness is about 1 nm.

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.
