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…
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 sta…
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…
