Anisotropic long-range spin transport in canted antiferromagnetic orthoferrite YFeO
Shubhankar Das, A. Ross, X. X. Ma +15
In antiferromagnets, the efficient propagation of spin-waves has until now only been observed in the insulating antiferromagnet hematite, where circularly (or a superposition of pa…
Second order Zeeman interaction and ferroquadrupolar order in TmVO
I. Vinograd, K. R. Shirer, P. Massat +7
TmVO exhibits ferroquadrupolar order of the Tm 4f electronic orbitals at low temperatures, and is a model system for Ising nematicity that can be tuned continuously to a quan…
NMR evidence against a spin-nematic nature of the presaturation phase in the frustrated magnet SrZnVO(PO4)2
K. M. Ranjith, F. Landolt, S. Raymond +2
Using P nuclear magnetic resonance (NMR) we investigate the recently discovered presaturation phase in the highly frustrated two-dimensional spin system SrZnVO(PO) […
Weak antilocalization and Shubnikov-de Haas oscillations in CaCuSb single crystal
Souvik Sasmal, Vikas Saini, Nicolas Bruyant +5
Quantum oscillations in both linear and Hall resistivities and weak antilocalization (WAL) are barely observed in bulk single crystals. Here we report the transport properties of a…
Specific Heat of the Kagome Antiferromagnet Herbertsmithite in High Magnetic Fields
Q. Barthélemy, A. Demuer, C. Marcenat +7
Measuring the specific heat of herbertsmithite single crystals in high magnetic fields (up to T) allows us to isolate the low-temperature kagome contribution while shifting aw…
Possible quadrupole density wave in the superconducting Kondo lattice CeRh2As2
D. Hafner, P. Khanenko, E. -O. Eljaouhari +12
CeRh2As2 has recently been reported to be a rare case of multi-phase unconventional superconductor [S. Khim et al., arXiv:2101.09522] close to a quantum critical point (QCP). Here,…
Feedback of superconductivity on the magnetic excitation spectrum of UTe
S. Raymond, W. Knafo, G. Knebel +5
We investigate the spin dynamics in the superconducting phase of UTe by triple-axis inelastic neutron scattering on a single crystal sample. At the wave-vector =(0,…
Magnetism in heavy-f-electron metals
William Knafo
In this document, I present a personal view on the heavy-fermion problem, within a phenomenological approach guided by experiments. This review presents a set of 'historical' works…
Edwards-Anderson parameter and local Ising-nematicity in FeSe revealed via NMR spectral broadening
Paul Wiecki, Rui Zhou, Marc-Henri Julien +2
The NMR spectrum of FeSe shows a dramatic broadening on cooling towards the bulk nematic phase at K, due to the formation of a quasi-static, short-range-ordered nematic do…
Low-dimensional antiferromagnetic fluctuations in the heavy-fermion paramagnetic ladder UTe
W. Knafo, G. Knebel, P. Steffens +7
Inelastic-neutron-scattering measurements were performed on a single crystal of the heavy-fermion paramagnet UTe above its superconducting temperature. We confirm the presence…
Neutron diffraction of field-induced magnon condensation in the spin-dimerized antiferromagnet SrCrO
Alsu Gazizulina, Diana Lucia Quintero-Castro, Zhe Wang +11
In this work, we investigate the evolution and settling of magnon condensation in the spin-1/2 dimer system SrCrO using a combination of magnetostriction in pulse…
Evidence for nesting driven charge density waves instabilities in a quasi-two-dimensional material: LaAgSb2
Alexeï Bosak, Sofia-Michaela Souliou, Clément Faugeras +6
Since their theoretical prediction by Peierls in the 30s, charge density waves (CDW) have been one of the most commonly encountered electronic phases in low dimensional metallic sy…
Formation of an electron-phonon bi-fluid in bulk antimony
Alexandre Jaoui, Adrien Gourgout, Gabriel Seyfarth +4
The flow of charge and entropy in solids usually depends on collisions decaying quasiparticle momentum. Hydrodynamic corrections can emerge, however, if most collisions among quasi…
Unidirectional Kondo scattering in layered NbS2
Edoardo Martino, Carsten Putzke, Markus König +13
Crystalline defects can modify quantum interactions in solids, causing unintuitive, even favourable, properties such as quantum Hall effect or superconducting vortex pinning. Here…
Origin of the 30 T transition in CeRhIn in tilted magnetic fields
S. Mishra, D. Gorbunov, D. J. Campbell +9
We present a comprehensive ultrasound study of the prototypical heavy-fermion material CeRhIn, examining the origin of the enigmatic 30 T transition. For a field applied at 2$^…

We report the magnetoresistance in the novel spin-triplet superconductor UTe2 under pressure close to the critical pressure Pc, where the superconducting phase terminates, for fiel…
Revealing three-dimensional quantum criticality by Sr-substitution in Han Purple
Stephan Allenspach, Pascal Puphal, Joosep Link +20
Classical and quantum phase transitions (QPTs), with their accompanying concepts of criticality and universality, are a cornerstone of statistical thermodynamics. An exemplary cont…
