Abstract

fetched live from OpenAlex

Magnetic van der Waals materials provide a rich venue for two-dimensional magnetism. Here, the authors study heterobilayers with a moir\'e pattern comprised of one ferromagnetic layer and one antiferromagnetic layer, with a Dzyaloshinskii-Moriya interaction in the ferromagnetic layer. Combining perturbative and strong-coupling analyses with numerical optimization, they uncover a rich phase diagram containing diverse moir\'e-periodic commensurate and incommensurate phases. This includes an interesting state with a nontrivial topological texture: a skyrmion lattice on the moir\'e scale.

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.

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.
