Abstract

The layered WHM-type ($W=\mathrm{Zr}/\mathrm{Hf}/\mathrm{La}, H=\mathrm{Si}/\mathrm{Ge}/\mathrm{Sn}/\mathrm{Sb}, M=\mathrm{S}/\mathrm{Se}/\mathrm{Te}$) materials represent a large family of topological semimetals, which provides an excellent platform to study the evolution of topological semimetal state with the fine tuning of spin-orbit coupling and structural dimensionality for various combinations of $W, H$, and $M$ elements. In this work, through high field de Haas--van Alphen (dHvA) quantum oscillation studies, we have found evidence for the predicted topological nontrivial bands in ZrSnTe. Furthermore, from the angular dependence of quantum oscillation frequency, we have revealed the three-dimensional Fermi surface topologies of this layered material owing to strong interlayer coupling.

  • Additional frequencies attributed to magnetic breakdown have been observed in high-field quantum oscillation studies on several topological semimetals.

    “The additional frequencies ascribed to magnetic breakdown have been observed in high-field quantum oscillation studies on several topological semimetals (171,226,252).”

    From Transport of Topological Semimetals (2019) · cites this paper as [226]

    The ZrSnTe results (p. 5) report multiple frequencies in high-field quantum oscillations, supporting the observation of additional frequencies in a topological semimetal. The paper attributes the measured frequencies to topological bands, not magnetic breakdown; a search for “magnetic breakdown” found no passage making that attribution. This source alone also does not establish observations in several semimetals. (LLM, conf=0.84)

  • Using WHMs as a platform for quantum spin Hall insulators may offer a variable spin-orbit-coupling gap with different W, H, and M combinations, enabling design of different quantum spin Hall insulators.

    “One possible advantage of using WHMs as a platform for realizing QSHIs is the variable SOC gap with various combinations of W, H, and M (226); such a gap offers the opportunity to design different QSHIs.”

    From Transport of Topological Semimetals (2019) · cites this paper as [226]

    The discussion on p. 9 says that changing the W, H, and M elements can fine-tune spin–orbit coupling in WHM compounds and that their symmetry allows an SOC gap. It discusses WHMs as topological semimetals, however, and does not propose using that gap to realize quantum spin Hall insulators. (LLM, conf=0.85)

    Experimental — accuracy not yet measured
  • Another phenomenon directly associated with electron condensation to the zeroth LL in topological semimetals is anomalous magnetization.

    “Another phenomenon directly associated with electron condensation to the zeroth LL in topological semimetals is anomalous magnetization (224).”

    From Transport of Topological Semimetals (2019) · cites this paper as [224]

    The discussion on p. 2 mentions interlayer quantum tunneling from the zeroth Landau level, while p. 4 reports magnetic-torque oscillations in ZrSnTe. Neither passage links electron condensation into the zeroth Landau level to anomalous magnetization. Searches for that link and for magnetization at the quantum limit found no supporting passage in our copy. (LLM, conf=0.76)

  • The magnetic torque anomaly observed in NbAs can be quantitatively described by the topological character of the electronic dispersion.

    “Indeed, the magnetic torque anomaly, which has been observed in NbAs, can be quantitatively described by the topological character of the electronic dispersion ( 224).”

    From Transport of Topological Semimetals (2019) · cites this paper as [224]

    The quantum-oscillation section (pp. 4–5) discusses magnetic-torque measurements and topological bands in ZrSnTe, not a torque anomaly in NbAs. A search for NbAs and a quantitative explanation of its torque anomaly found only a NbAs magnetotransport citation in the references (p. 11). (LLM, conf=0.76)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
