Resonance-Induced Anomalies in Temperature-Dependent Raman Scattering of PdSe
Omar Abdul-Aziz, Daniel Wolverson, Charles Sayers +4
We report a comprehensive Raman study of the phonon behaviour in PdSe in the temperature range of 5 K to 300 K. A remarkable change in the Raman spectrum is observed at 120 K:…
Nonequilibrium dynamics of -RuCl -- a time-resolved magneto-optical spectroscopy study
Julian Wagner, Anuja Sahasrabudhe, Rolf Versteeg +5
We present time-resolved magneto-optical spectroscopy on the magnetic Mott-Hubbard-insulating Kitaev spin liquid candidate -RuCl to investigate the nonequilibrium dynamics o…
Magneto-optical study of metamagnetic transitions in the antiferromagnetic phase of -RuCl
Julian Wagner, Anuja Sahasrabudhe, Rolf Versteeg +7
-RuCl is a promising candidate material to realize the so far elusive quantum spin liquid ground state. However, at low temperatures, the coexistence of different exchange i…
Nonequilibrium quasistationary spin disordered state in the Kitaev-Heisenberg magnet -RuCl
R. B. Versteeg, A. Chiocchetta, F. Sekiguchi +9
Excitation by light pulses enables the manipulation of phases of quantum condensed matter. Here, we photoexcite high-energy holon-doublon pairs as a way to alter the magnetic free…
Coupled dynamics of long-range and internal spin cluster order in CuOSeO
R. B. Versteeg, J. Zhu, C. Boguschewski +7
Cu triplet clusters form the relevant spin entity for the formation of long-range magnetic order in the cluster magnet CuOSeO. Using time-resolved Raman spectroscopy, w…
High-field recovery of the undistorted triangular lattice in the frustrated metamagnet CuFeO2
T. T. A. Lummen, C. Strohm, H. Rakoto +2
Pulsed field magnetization experiments extend the typical metamagnetic staircase of CuFeO2 up to 58 T to reveal an additional first order phase transition at high field for both th…
