Ultrasound Evidence for a Low-Temperature Anomaly Inside the Superconducting State of 4Hb-TaS
Yongwei Li, Dmitri V. Efremov, Paul Leask +7
We report low-temperature ultrasound measurements on single crystals of the layered van der Waals superconductor 4Hb-TaS. Specific heat and ac magnetic susceptibility show a sh…
Thermodynamic Evidence of Tetracritical Topology in the - Phase Diagram of UTe for
Michal Vališka, Tetiana Haidamak, Andrej Cabala +4
We report ultrasound velocity measurements on an ultraclean UTe single crystal with ~K for , performed up to 18~T and down to 0.33~K. The measurements pro…
Contrasting magnetic behavior in MnSc_2X_4 (X = S, Se) spinel compounds investigated by magnetoelastic studies
J. Grumbach, J. Sourd, M. Deeb +12
The spinel compounds MnSc_2X_4 are highly frustrated and candidate materials for vortex-like 3q magnetic states, such as skyrmions, with propagation vectors in the [111] plane. Bec…
Spin-strain interactions under hydrostatic pressure in -RuCl
A. Hauspurg, Susmita Singh, T. Yanagisawa +5
We investigate the effects of hydrostatic pressure on -RuCl, a prototypical material for the Kitaev spin model on a honeycomb lattice with a possible spin-liquid ground stat…
Ultrasound measurement technique for the single-turn-coil magnets
T. Nomura, A. Hauspurg, D. I. Gorbunov +7
Ultrasound is a powerful means to study numerous phenomena of condensed-matter physics as acoustic waves couple strongly to structural, magnetic, orbital, and charge degrees of fre…
Excitation Spectrum and Spin Hamiltonian of the Frustrated Quantum Ising Magnet PrBWO
J. Nagl, D. Flavián, S. Hayashida +16
We present a thorough experimental investigation on single crystals of the rare-earth based frustrated quantum antiferromagnet PrBWO, a purported spin-liquid candidate on t…
Pressure-tuned quantum criticality in the large- antiferromagnet DTN
Kirill Yu. Povarov, David E. Graf, Andreas Hauspurg +11
Strongly correlated spin systems can be driven to quantum critical points via various routes. In particular, gapped quantum antiferromagnets can undergo phase transitions into a ma…
Fractionalized Excitations Probed by Ultrasound
A. Hauspurg, S. Zherlitsyn, T. Helm +8
In this work, we study magnetoelastic interactions by means of ultrasound experiments in -RuCl -- a prototypical material for the Kitaev spin model on the honeycomb lattice,…
