Abstract

Superconducting high-entropy alloys (HEAs) are a newly burgeoning field of unconventional superconductors and raise intriguing questions about the presence of superconductivity in highly disordered systems, which lack regular phonon modes. In our study, we have synthesized and investigated the superconducting characteristics of two new transition elements based HEAs Re 0.35 Os 0.35 Mo 0.10 W 0.10 Zr 0.10 crystallizing in noncentrosymmetric α -Mn structure, and Ru 0.35 Os 0.35 Mo 0.10 W 0.10 Zr 0.10 crystallizing in hexagonal closed-packed structure (hcp). Due to its high hardness, transition-metal-based hexagonal hcp HEA is rare and highly desirable for practical applications. Bulk magnetization, resistivity, and specific heat measurements confirmed bulk type-II superconductivity in both alloys. Specific heat analysis up to the measured low-temperature range suffices for a Bardeen-Cooper-Schrieffer explanation.

  • The μ0Hc2(0) exceeding the Pauli paramagnetic limit was also found in BCC-type ScVTiHfNb, HCP-type Ru0.35Os0.35Mo0.12W0.1Zr0.1, A15-type (Nb0.5V0.5)3-xMoxAl0.5Ga0.5, and α-Mn-type Ru0.35Os0.35Mo0.1W0.1Zr0.1 HEA superconductors.

    From Recent advances in high-entropy superconductors (2024) · cites this paper as [89]

    The Introduction (p. 1) and Conclusion (p. 6) report upper critical fields exceeding the Pauli limit for the paper’s two alloys. But the alloy it identifies as hexagonal is Ru0.35Os0.35Mo0.10W0.10Zr0.10, not the cited Mo0.12 composition; its α-Mn alloy is Re0.35Os0.35Mo0.08W0.10Zr0.12, not the cited Ru alloy. The BCC and A15 examples have separate citations and are not attributed to this source. (LLM, conf=0.91)

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.
