Growth and magnetic properties of epitaxial ultrathin Ni films on Cu(111) using Sb as a surfactant
Bibliographic record
Abstract
We studied the growth and magnetism of ultrathin Ni films on the (111) surface of Cu using Sb as a surfactant. For this purpose we deposited Sb under UHV conditions at room temperature onto the Cu surface prior to the Ni film growth. When the Sb precoverage exceeded a certain threshold [0.7 monolayers (ML)], pronounced intensity oscillations of the medium energy electron diffraction signal indicated a layer-by-layer growth of the deposited Ni films. Low energy electron diffraction patterns of the Ni films revealed a hexagonal structure with a threefold symmetry. Using this approach we prepared high quality epitaxial Ni(111) films up to a thickness of 20 ML and performed in situ magneto-optical Kerr measurements. At a thickness of 7–8 ML an inverse spin reorientation transition occurs from an in-plane magnetization at lower thicknesses to an out-of-plane orientation for higher thicknesses.

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.
