Quantifying thermal and driven magnon populations with femtosecond noise correlation spectroscopy
F. S. Herbst, M. A. Weiss, A. Leitenstorfer +5
Precise knowledge of the total number of magnons, including both coherent and incoherent (e.g. thermal) excitations, is imperative for the advancement of fundamental spin-wave phys…

Field-tuning of ultrafast magnetization fluctuations in SmErFeO
Marvin Alexander Weiss, Julius Schlegel, Daniel Anić +7
The properties of spin fluctuations in antiferromagnets are largely unexplored, in particular at ultrafast timescales. Here, we employ femtosecond noise correlation spectroscopy (F…
