Magnetization processes and spin dynamics across field-induced phase transitions in the quasi-two-dimensional quantum magnet Cu(OH)Br
Anneke Reinold, Dirk Wulferding, Laur Peedu +13
We present magnetic-field-dependent evolution of magnetization and spin dynamics in the quasi-two-dimensional spin- magnet , consisting of alternately c…
Giant quantum oscillations in thermal transport in low-density metals via electron absorption of phonons
B. Bermond, R. Wawrzynczak, S. Zherlitsyn +14
Oscillations of conductance observed in strong magnetic fields are a striking manifestation of the quantum dynamics of charge carriers in solids. The large charge carrier density i…
Dramatic elastic response at the critical end point in UTe
Michal Vališka, Tetiana Haidamak, Andrej Cabala +10
The first-order transition line in the \textit{H-T} phase diagram of itinerant electron metamagnets terminates at the critical end point-analogous to the critical point on the gas-…
Signatures of a magnetic-field-induced Lifshitz transition in the ultra-quantum limit of the topological semimetal ZrTe
S. Galeski, H. F. Legg, R. Wawrzyńczak +10
The quantum limit (QL) of an electron liquid, realised at strong magnetic fields, has long been proposed to host a wealth of strongly correlated states of matter. Electronic states…
Multi-Center Magnon Excitations Open the Entire Brillouin Zone to Terahertz Magnetometry of Quantum Magnets
Tobias Biesner, Seulki Roh, Aleksandar Razpopov +14
Due to the small photon momentum, optical spectroscopy commonly probes magnetic excitations only at the center of the Brillouin zone; however, there are ways to override this restr…
Coexistence of antiferromagnetism and ferrimagnetism in adjacent honeycomb layers
D. Szaller, L. Prodan, K. Geirhos +12
Antiferromagnetic and ferro/ferrimagnetic orders are typically exclusive in nature, thus, their co-existence in atomic-scale proximity is expected only in heterostructures. Breakin…
Propagation of longitudinal acoustic phonons in ZrTe exposed to a quantizing magnetic field
Toni Ehmcke, Stanislaw Galeski, Denis Gorbunov +4
The compound ZrTe has recently been connected to a charge-density-wave (CDW) state with intriguing transport properties. Here, we investigate quantum oscillations in ultrasound…
