Insight into high-entropy effect in body-centered cubic superconducting alloys
Hanabusa Senga, Yuto Watanabe, Fubuki Iwase +6
We have characterized the superconducting critical temperature (), the Debye temperature (), the electronic specific heat coefficient, and the Vickers m…
Enhanced in eutectic high-entropy alloy superconductors Hf-Nb-Sc-Ti-Zr
Issei Kubo, Yuto Watanabe, Shuma Kawashima +4
The present investigation into the superconducting properties of eutectic high-entropy alloy (HEA) Hf-Nb-Sc-Ti-Zr systems reveals an enhanced superconducting critical temperature (…
Spontaneous superconducting diode effect in non-magnetic Nb/Ru/SrRuO topological junctions
M. S. Anwar, T. Nakamura, R. Ishiguro +5
Non-reciprocal electronic transport in a material occurs if both time reversal and inversion symmetries are broken. The superconducting diode effect (SDE) is an exotic manifestatio…
Fully-gapped superconducting state in interstitial-carbon-doped Zr5Pt3
T. Shang, J. Philippe, X. Y. Zhu +6
We report a comprehensive study of the ZrPtC superconductors, with interstitial carbon comprised between 0 and 0.3. At a macroscopic level, their superconductivity, wit…
Superconductivity in Al-Nb-Ti-V-Zr multicomponent alloy

Cutting edge of high-entropy alloy superconductors from the perspective of materials research
Jiro Kitagawa, Shusuke Hamamoto, Naoki Ishizu
High-entropy alloys (HEAs) are a new class of materials which are being energetically studied around the world. HEAs are characterized by a multi-component alloy in which five or m…
Multiple- to single-gap superconductivity crossover in NbIrPtO alloys
Y. Xu, S. Jöhr, L. Das +5
By using mostly the muon-spin rotation/relaxation (SR) technique, we investigate the superconductivity (SC) of NbIrPtO ( and 1.6) alloys, with $T_c = 10.5…
Superconductivity in Nb5Ir3-xPtxO
Jiro Kitagawa, Shusuke Hamamoto
We have investigated the superconducting critical temperature Tc of solid solution Nb5Ir3-xPtxO with the Ti5Ga4-type structure. The both end-members of Nb5Ir3O and Nb5Pt3O are repo…
New high-entropy alloy superconductor HfNbTiVZr
