Abstract
Abstract Monolayer iron germanium telluride Fe 3 GeTe 2 , one of the typical two-dimensional ferromagnetic materials, hitherto, has only been studied by exfoliated micron-sized samples. We achieve high-quality wafer-scale growth of thin Fe 3 GeTe 2 films by molecular beam epitaxy, greatly expanding the types of characterization tools employable and providing the possibility for its integration in devices like consumer electronics. Thickness-dependent transport measurements are used to characterize and probe for magnetic order. Ferromagnetic states exist in 1–10 layer thick Fe 3 GeTe 2 , with Curie temperatures ranging from ~75 K in one layer samples to above 175 K in ten layer samples. A single ferromagnetic phase with significant magnetic anisotropy is revealed for all layer numbers. We submit the capability of synthesizing, wafer-scale Fe 3 GeTe 2 as an essential step towards its fulfillment in any applications involving magnetism, such as spintronics.

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 it
