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…
Multi-probe detection of domain nucleation across the metal-insulator transition in VO
Shubhankar Paul, Giordano Mattoni, Amitava Ghosh +7
Electronic and structural degrees of freedom are often intimately coupled in strongly correlated systems, which result in intriguing macroscopic and microscopic phenomena. Using th…
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…
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…
