  • The Ta-Hf-Nb-Zr-Ti system has emerged as the most extensively investigated BCC-type HEA superconductor.

    “The Ta-Hf-Nb-Zr-Ti system has emerged as the most extensively investigated BCC-type HEA superconductor 9 -17 .”

    From Recent advances in high-entropy superconductors (2024) · cites this paper as [16]

    The introductory passage (indexed under Abstract; page unavailable) identifies Ti-Zr-Hf-Nb-Ta as the system in which the first HEA superconductor was reported and notes growing research on HEA superconductors. It does not say that this system is the most extensively investigated BCC-type HEA superconductor; that comparative claim is unsupported by our copy. (LLM, conf=0.82)

  • The normalized Cel jumps at Tmidc (ΔCel/γnTmidc) and Tzeroc (ΔCel/γnTzeroc) for the TiHfNbTa superconductor are 2.88 and 2.13, respectively.

    “The normalized Cel jumps at T mid c ( Δ Cel/ γ n T mid c ) and T zero c ( Δ Cel/ γ n T zero c ) for the TiHfNbTa superconductor are 2.88 and 2.13, respectively.”

    From Recent advances in high-entropy superconductors (2024) · cites this paper as [16]

  • Both ΔCel/γnTc values in the TiHfNbTa superconductor significantly exceed the BCS weak coupling ratio (1.43), thereby suggesting strong coupling in TiHfNbTa.

    “Both Δ Cel/ γ n T c values in the TiHfNbTa superconductor signi fi cantly exceed the BCS weak coupling ratio (1.43), thereby suggesting strong coupling in TiHfNbTa.”

    From Recent advances in high-entropy superconductors (2024) · cites this paper as [16]

  • Extremely strong coupling behavior was also observed in TiHfNbTa superconductors.

    “In addition, extremely strong coupling behavior was also observed in TiHfNbTa superconductors 16 .”

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.
