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…
