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…

Search for magnetoacoustic quantum oscillations in the insulating phase of YbB

Ryosuke Kurihara, Atsuhiko Miyata, Koji Araki +9

A highly exotic phenomenon in solid-state physics is the observation of magnetic quantum oscillations in insulators. For instance, in the Kondo insulator YbB various groups…

Magnetoelastic signatures of the conical state and charge density waves in antiferromagnetic FeGe

L. Prodan, J. Sourd, S. Zherlitsyn +1

Kagome systems host intertwined spin, charge, and lattice degrees of freedom that drive emergent collective states. Here, we identify two distinct energy scales in the noncollinear…

Investigation of CeRhAs order parameters via ultrasound propagation anomalies

S. Galeski, C. Lee, F. Bartl +11

Unconventional superconductors with nearly degenerate pairing states are rare. CeRhAs has recently emerged as one of the few existing multi-phase superconductors. It exhibi…

Magnetoelastic coupling at the field-induced transition in EuAlO

T. Haidamak, G. Bastien, P. Proschek +9

Magnetoelastic coupling plays a crucial role in magnetic-field-induced transitions in anisotropic ferromagnets. Ultrasonic methods are suitable for experimental investigations of t…
