Abstract

fetched live from OpenAlex

A study is made of the role of surface orientation in determining the spectra of surface spin waves in antiferromagnetic films. The calculations apply to the exchange-dominated regime and are based on a spin-wave operator and Green-function technique. The method exploits some properties of banded (tridiagonal and pentadiagonal) matrices in order to find analytical expressions for the spin-wave frequencies. Theoretical results are presented for films with a simple cubic structure and surfaces corresponding to three different orientations of the crystal planes, namely, (001), (011), and (111), for which the surface spin-wave characteristics are found to be quite distinct. This work generalizes previous calculations for semi-infinite simple cubic antiferromagnets with (001) surfaces.

Full frame distilled prediction

Teacher imitation

Not 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.
