Superconductivity on the verge of metal-insulator transition in CuZnIrS probed by SR

K. M. Kojima, M. Miyazaki, M. Hiraishi +6

The thiospinel CuIrS undergoes a metal-insulator transition below 230 K, which is suppressed by substitution of Cu with Zn (CuZnIrS) to induce…

Type-II superconductivity in the Dirac semimetal PdTe2

Ritu Gupta, Catherine Witteveen, Debarchan Das +2

We report on the microscopic superconducting properties of the Dirac semimetal PdTe2. In this study, we have focused on mosaic crystals of PdTe2, and used detailed zero field and t…

Capturing nuclear quantum effects in high-pressure superconducting hydrides and ice with nuclear-electronic orbital theory

Logan E. Smith, Paolo Settembri, Alessio Cucciari +3

Nuclear quantum effects are essential for correctly describing hydrogen-rich materials at high pressures. Superconducting hydrides and ice are prime examples of such systems, requi…

Niobium's intrinsic coherence length and penetration depth revisited using low-energy muon spin spectroscopy and secondary-ion mass spectrometry

Ryan M. L. McFadden, Jonathan W. Angle, Eric M. Lechner +7

We report direct, simultaneous measurements of the London penetration depth () and Bardeen-Cooper-Schrieffer (BCS) coherence length () in oxygen-doped niobium, with impur…
