Thermal properties of surface and bulk spin waves in uniaxial and nonuniaxial metamagnetic films
Bibliographic record
Abstract
A theory is presented for the temperature dependence of surface and bulk spin waves in metamagnetic films, allowing for the inclusion of both uniaxial and nonuniaxial contributions to the single-ion anisotropy. A Green's function formalism is employed to evaluate spin-wave dispersion relations and the mean square amplitudes of spin-wave modes. The theory is applied to obtain numerical results for the $S=\mathrm{1}$ metamagnets $\mathrm{Fe}{\mathrm{Br}}_{2}$ and $\mathrm{Fe}{\mathrm{Cl}}_{2}$ in both the antiferromagnetic and ferromagnetic phases, depending on the strength of the applied magnetic field. The case of ultrathin films with a relatively small number of atomic layers is considered, as well as that of thicker films.

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.
