Thermodynamic and transport properties of high-quality single crystals of the altermagnet CrSb
Shubhankar Paul, Atsutoshi Ikeda, Giordano Mattoni +2
Altermagnetism (AM) is an emerging magnetic order unifying essential characteristics of ferromagnetic and antiferromagnetic states. The CrSb has attracted significant interest owin…
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…
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…
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…
