Emergence of a Fluctuating Ground State in Y-kapellasite under Pressure
Dipranjan Chatterjee, Petr Doležal, Federico Abbruciati +17
Y-kapellasite (YCu(OH)Cl), which hosts an original anisotropic kagome sublattice, is a promising candidate for studying elusive and complex correlated physics. I…
Lattice dynamics of the frustrated kagome compound Y-kapellasite
P. Doležal, T. Biesner, Y. Li +6
Studying the magnetic ground states of frustrated antiferromagnets provides unique insight into the stability of quantum spin liquids, even if the anticipated state is not realized…
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…
Magnetic terahertz resonances above the Néel temperature in the frustrated kagome antiferromagnet averievite
Tobias Biesner, Seulki Roh, Andrej Pustogow +3
Time-domain magneto-THz spectroscopy is utilized to study the frustrated magnet averievite CuZnVO(CsCl). Pronounced THz resonances are observed in unsubstitu…
Magnetic-order-driven metal-insulator transitions in the quasi-one-dimensional spin-ladder compounds BaFeS and BaFeSe
Seulki Roh, Soohyeon Shin, Jaekyung Jang +9
The quasi-one-dimensional spin ladder compounds, BaFeS and BaFeSe, are investigated by infrared spectroscopy and density functional theory (DFT) calculations. We ob…
Detuning the Honeycomb of -RuCl: Pressure-Dependent Optical Studies Reveal Broken Symmetry
Tobias Biesner, Sananda Biswas, Weiwu Li +10
The honeycomb Mott insulator -RuCl loses its low-temperature magnetic order by pressure. We report clear evidence for a dimerized structure at GPa and observe the brea…
