Fermi-liquid behavior and characteristic temperature-dependent susceptibility in clean RuO crystal
Shubhankar Paul, Atsutoshi Ikeda, Hisakazu Matsuki +6
The magnetic nature of the altermagnet candidate RuO remains under debate. It has been recently shown from quantum oscillations and angle-resolved photoemission spectroscopy (A…
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 thi…
Growth of ultra-clean single crystals of RuO2
Shubhankar Paul, Giordano Mattoni, Hisakazu Matsuki +4
We report the details of the growth of ultra-clean single crystals for RuO2, a candidate material for altermagnetism. By using a crystal-growth tube with a necking structure and pr…
The Fermi surface of RuO2 measured by quantum oscillations
Zheyu Wu, Mengmeng Long, Hanyi Chen +12
The metallic oxide RuO has emerged as a promising altermagnet candidate, owing to reports of this material hosting antiferromagnetic ordering accompanied by a spin-split electr…
