Muon Knight shift as a precise probe of the superconducting symmetry of SrRuO
Hisakazu Matsuki, Rustem Khasanov, Jonas A. Krieger +8
Muon spin rotation (SR) measurements of internal magnetic field shifts, known as the muon Knight shift, is used for determining pairing symmetries in superconductors. While this…

We report the results of resistance measurements under pressure up to on single-crystalline , which shows the maximum of superconducting trans…
Direct evidence for the absence of coupling between shear strain and superconductivity in Sr2RuO4
Giordano Mattoni, Thomas Johnson, Atsutoshi Ikeda +4
The superconducting symmetry of Sr2RuO4 has been intensely debated for many years. A crucial controversy recently emerged between shear-mode ultrasound experiments, which suggest a…
Still mystery after all these years -- Unconventional superconductivity of Sr2RuO4 --
Yoshiteru Maeno, Shingo Yonezawa, Aline Ramires
This review describes recent significant research developments made on the layered perovskite Sr2RuO4 and discusses current issues from both experimental and theoretical perspectiv…
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…
Spin fluctuations in Sr2RuO4 from polarized neutron scattering: implications for superconductivity
P. Steffens, Y. Sidis, J. Kulda +4
Triplet pairing in Sr2RuO4 was initially suggested based on the hypothesis of strong ferromagnetic spin fluctuations. Using polarized inelastic neutron scattering, we accurately de…
