Successive Electronic Topological Transitions in the Antiferromagnet UPdAl
Adrien Gourgout, Gaël Bastien, Dai Aoki +7
We report successive anomalies at low temperature in the magnetic field dependence of the thermoelectric signal in the heavy fermion compound UPdAl inside the antiferro…
Unusual upper critical field in UTe2 revealed by magnetotransport measurements up to 42 T
Macha Méplan, Ilya Sheikin, Pierre Pugnat +16
The heavy-fermion superconductor UTe2 is unique in that, at ambient pressure, it exhibits three distinct superconducting phases, two of which are induced by magnetic field. When th…
Surface charge density wave in UTe2
Pablo GarcÃa Talavera, Pablo García Talavera, Miguel Ãgueda Velasco +16
The spatially uniform electronic density characteristic of a metal can become unstable at low temperatures, leading to the formation of charge density waves (CDWs). These CDWs, obs…
Metastability of the Topological Magnetic Orders in the Chiral Antiferromagnet EuPtSi
Simon Rousseau, Gabriel Seyfarth, Georg Knebel +3
We report resistivity and Hall effect measurements in the chiral antiferromagnet EuPtSi. Depending on the magnetic field orientation with respect to the crystallographic axes, EuPt…
Slow magnetic quantum oscillations in the c-axis magnetoresistance of UTe
Freya Husstedt, Motoi Kimata, Sajal Naduvile Thadathil +8
Details of the electronic band structure in unconventional superconductors are key to the understanding of their fundamental ground state. The potential spin-triplet superconductor…
Incommensurate and commensurate antiferromagnetic orders in the kagome compound UVSn
Midori Amano Patino, Stephane Raymond, Georg Knebel +12
We report on the synthesis of single crystals of the kagome compound, UVSn, and present the results of magnetization, electrical resistivity, heat capacity, x-ray, and neut…
