Spin-orbit-entangled $J_{eff} = \frac{1}{2}$ magnetism and unconventional spin freezing in the bond-disordered pyrochlore antiferromagnet NaCdCo $_{2}$ F $_{7}$

Andrej Kancko, Hironori Sakai, Javier Herrero-MartÃn +5

Bond disorder in frustrated pyrochlore antiferromagnets can give rise to fundamentally different quantum ground states depending on the nature of the local magnetic moments. Here,…

Thermodynamic Evidence of Tetracritical Topology in the $H$ - $T$ Phase Diagram of UTe $_{2}$ for $H ∥ b$

Michal ValiÅ¡ka, Michal Vališka, Tetiana Haidamak +6

We report ultrasound velocity measurements on an ultraclean UTe $_{2}$ single crystal with $T_{c} > 2$ ~K for $H ∥ b$ , performed up to 18~T and down to 0.33~K. The measurements pro…

Strange metallicity encompasses high magnetic field-induced superconductivity in UTe2

T. I. Weinberger, H. Chen, Z. Wu +9

A strange metallic state - characterized by an electrical resistivity that rises linearly in temperature $T$ at a rate governed by Planckian energetic dissipation - is present in a…

A frustrated antipolar phase analogous to classical spin liquids

G. Bastien, D. RepÄek, A. EliÃ¡Å¡ +17

The study of magnetic frustration in classical spin systems was motivated by the prediction and discovery of classical spin liquid states. These uncommon magnetic phases are charac…

Quasi-two-dimensional ferromagnetism in the triangular magnet EuAl $_{12}$ O $_{19}$

G. Bastien, Q. Courtade, A. EliÃ¡Å¡ +6

We report ferromagnetic ordering at $T_{C} = 1.3$ K in the quasi-two dimensional magnet EuAl $_{12}$ O $_{19}$ with large spins $S = 7/2$ . This ferromagnetic state was characteri…
