Nonequilibrium spin dynamics in the chiral soliton lattice host YbNi3Al9
Bibliographic record
Abstract
The uniaxial chiral magnetic material YbNi3Al9 is proposed as a chiral soliton lattice (CSL) host. In this study, we thoroughly investigate the spin dynamics in YbNi3Al9 single crystals using magnetization (M)-relaxation and electron spin resonance (ESR) techniques. The M-relaxation analysis unambiguously reveals characteristics of a nonequilibrium CSL in YbNi3Al9. A prolonged relaxation is observed in the ferromagnetic-rich-CSL state, indicating nonequilibrium spin dynamics during the annihilation or nucleation of chiral magnetic solitons, in accordance with the unfrustrated magnetic cluster model. The ESR study shows significant microwave responses when the magnetic field is applied perpendicular to the c-axis (H ⊥ c), whereas a weak response is observed when the field is aligned with the c-axis (H//c). Two resonance lines are identified for H ⊥ c. The resonance signal at lower fields is attributed to the Goldstone excitation of chiral magnetic solitons, while the signal at higher fields is associated with ferromagnetic resonance. These findings enhance the understanding of nonequilibrium spin dynamics of the CSL in YbNi3Al9 single crystals and are beneficial for the application of chiral magnetic solitons in spintronics.

Full frame machine prediction
Teacher imitationNot 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.
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 source (direct Gemma or distilled Codex), not a consensus.
