Origin of the Anomalous Electrical Transport Behavior in Fe‐Intercalated Weyl Semimetal T<sub>d</sub>‐MoTe<sub>2</sub>
Bibliographic record
Abstract
Abstract Weyl semimetal T d ‐MoTe 2 has recently attracted much attention due to its intriguing electronic properties and potential applications in spintronics. Here, Fe‐intercalated T d ‐Fe x MoTe 2 single crystals (0 < x < 0.15 ) are grown successfully. The electrical and thermoelectric transport results consistently demonstrate that the phase transition temperature T S is gradually suppressed with increasing x . Theoretical calculation suggests that the increased energy of the T d phase, enhanced transition barrier, and more occupied bands in 1T′ phase is responsible for the suppression in T S . In addition, a ρ α –ln T behavior induced by Kondo effect is observed with x ≥ 0.08, due to the coupling between conduction carriers and the local magnetic moments of intercalated Fe atoms. For T d ‐Fe 0.15 MoTe 2 , a spin‐glass transition occurs at ≈10 K. The calculated band structure of T d ‐Fe 0.25 MoTe 2 shows that two flat bands exist near the Fermi level, which are mainly contributed by the d yz and orbitals of the Fe atoms. Finally, the electronic phase diagram of T d ‐Fe x MoTe 2 is established for the first time. This work provides a new route to control the structural instability and explore exotic electronic states for transition‐metal dichalcogenides.

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.
