Phonon polaritons in magnetoelectric multiferroics film: the possibility to drive surface modes using magnetic field
Bibliographic record
Abstract
In this paper, we report our numerical study of transverse mode phonon polaritons generated on magnetoelectric multiferroic films. The mathematical models of the dispersion relation for both surface and guided-wave modes were derived by solving the Maxwell equations. Then, numerical calculations were performed for various thicknesses using parameters suitable for illustrating magnetoelectric multiferroic BaMnF 4 . It was found that around the thicknesses of 0.1 mm–1 mm, the guided-wave modes were discreet. The surface phonon polaritons were obtained at the region between ferroelectric resonant frequency ω e and intercept frequency ω i . These surface modes were reciprocal, i.e., ω( k ) = ω(− k ). These results were in good agreement with the calculated attenuated total reflection spectra. It was also found numerically that the application of a magnetic field was able to shift the frequency of the surface phonon polaritons.

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.
