Electrical and thermal magnetotransport in altermagnetic CrSb

Sajal Naduvile Thadathil, Christoph MÃ¼ller, Reza Firouzmandi +20

Chromium antimonide has emerged as a key material platform for studying altermagnetism because of its simple binary composition, high NÃ©el temperature, and semimetallic electronic…

$H$ -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…

Fermi-surface studies of altermagnetic CrSb from Shubnikov-de Haas oscillations

Sajal Naduvile Thadathil, Beat Valentin Schwarze, Jaafar Ansari +13

Within the family of altermagnets, CrSb is a metallic, collinearly ordered material that exhibits particularly strong symmetry-induced spin splitting in its band structure. In this…

Fermi-liquid transport beyond the upper critical field in superconducting La $_{2}$ PrNi $_{2}$ O $_{7}$ thin films

Yu-Te Hsu, Yidi Liu, Yoshimitsu Kohama +7

Unconventional superconductivity typically emerges out of a strongly correlated normal state, manifesting as a highly renormalized Fermi liquid or a strange metal with $T$ -linear r…

Engineering altermagnetic symmetry to enable anomalous Hall response in Cr $_{1 - x}$ Mn $_{x}$ Sb

Miriam G. Fischer, Lukas Odenbreit, Olena Gomonay +13

Altermagnets are a promising class of materials for spintronic applications. However, compounds that simultaneously combine the symmetry required to support an anomalous Hall effec…

Doping dependence of the low temperature planar carrier density in overdoped YBa $_{2}$ Cu $_{3}$ O $_{7 - I^´}$

Rebecca Nicholls, Roemer Hinlopen, Jake Ayres +6

Whether a quantum critical point (QCP) demarcates the end of the pseudogap (PG) regime in hole-doped cuprates at a singular doping level $p^{*} \approx 0.19$ remains an open question…
