Electron-Hole Scattering Dichotomy and Anisotropic Warping in Quasi-Two-Dimensional Fermi Surfaces of UTe2

Motoi Kimata, Jun Ishizuka, Freya Husstedt +13

We present a combined experimental and theoretical study of the detailed Fermi-surface (FS) geometry of UTe2, a heavy-fermion superconductor that has recently attracted considerabl…

$H$ -linear magnetoresistance in the $T^{2}$ resistivity regime of overdoped infinite-layer nickelate La $_{1 - x}$ Sr $_{x}$ NiO $_{2}$

Yong-Cheng Pan, Tommy Kotte, Toni Helm +3

We report a systematic magnetotransport study on high-crystallinity La $_{1 - x}$ Sr $_{x}$ NiO $_{2}$ (LSNO) thin films with $x = 0.20 - 0.24$ . By conducting pulsed-field transport experiment…

Slow magnetic quantum oscillations in the c-axis magnetoresistance of UTe $_{2}$

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…
