Abstract

fetched live from OpenAlex

Abstract Weyl semimetal Td‐MoTe2 has recently attracted much attention due to its intriguing electronic properties and potential applications in spintronics. Here, Fe‐intercalated Td‐FexMoTe2 single crystals (0 < x < 0.15 ) are grown successfully. The electrical and thermoelectric transport results consistently demonstrate that the phase transition temperature TS is gradually suppressed with increasing x. Theoretical calculation suggests that the increased energy of the Td phase, enhanced transition barrier, and more occupied bands in 1T′ phase is responsible for the suppression in TS. In addition, a ρα–lnT 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 Td‐Fe0.15MoTe2, a spin‐glass transition occurs at ≈10 K. The calculated band structure of Td‐Fe0.25MoTe2 shows that two flat bands exist near the Fermi level, which are mainly contributed by the dyz and orbitals of the Fe atoms. Finally, the electronic phase diagram of Td‐FexMoTe2 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.

Not 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.
