Magnetic and acoustic excieations in confined nickel nanowires
Bibliographic record
Abstract
The magnetic and vibrational excitations of periodic arrays of Ni nanowires, in 1µmthick Al₂O₃ membranes on Al substrates, have been investigated by Brillouin scattering. Ni nanowires of 30 and 40 nm diameter and periodicity of 100 nm have been studied in a transverse magnetic field from 0-0.4 T. The p-s polarized spectra feature three peaks, with Brillouin frequencies below 20 GHz, and whose intensities are strongly dependent on the applied magnetic field and whose Stokes/anti-Stokes intensity ratios are unequal. These results indicate that the three peaks are magnetic in origin. A surface acoustic wave on the Ni-filled Al₂O₃ structures is also observed in p-p polarized spectra, with a phase velocity of about 3400 m/s for the 30nm-diameter nanowire sample.

How this classification was reachedexpand
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.
