Abstract

fetched live from OpenAlex

Realistic calculations of linear spin waves in thin ferromagnetic stripes are presented using a microscopic method based on a Hamiltonian approach. The theory, which is applicable to inhomogeneously magnetized samples, incorporates both the exchange and dipole-dipole interactions as well as effects of single-ion anisotropy and an external magnetic field applied either parallel or perpendicular to the stripe axis. This approach does not require the specification of phenomenological boundary conditions to study spin waves in these confined configurations. The Green's function theory is applied to Permalloy and nickel stripes to obtain the frequency, spatial distribution, and spectral intensity of discrete spin-wave modes. Through the spin-wave properties, the effective pinning parameters of the dynamic magnetization at the boundaries of the systems are deduced.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
