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…
Optically driven collective spin excitations and magnetization dynamics in the Néel-type skyrmion host GaVS
P. Padmanabhan, F. Sekiguchi, R. B. Versteeg +5
GaVS is a multiferroic semiconductor hosting magnetic cycloid (Cyc) and Néel-type skyrmion lattice (SkL) phases with a broad region of thermal and magnetic stability. Here,…
A tunable time-resolved spontaneous Raman spectroscopy setup for probing ultrafast collective excitation and quasiparticle dynamics in quantum materials
R. B. Versteeg, J. Zhu, P. Padmanabhan +5
We present a flexible and efficient ultrafast time-resolved spontaneous Raman spectroscopy setup to study collective excitation and quasi-particle dynamics in quantum matter. The s…
Dynamical resonance quench and Fano interference in spontaneous Raman scattering from quasiparticle and collective excitations
J. Zhu, R. B. Versteeg, P. Padmanabhan +1
Time-resolved spontaneous Raman spectroscopy serves as a probe for incoherent quasiparticle and collective excitation dynamics, and allows to distinguish symmetry changes across a…
