This data publication contains the data for our publication "Self-induced Floquet magnons in magnetic vortices". The dataset is structured in folders corresponding to the different figures in the paper. Folder Fig-2 contains the simulated spectra and the experimental spectra measured with Brillouin-light-scattering microscopy. The experimental spectra contain the data integrated for the measurement positions described in the methods section. Folder Fig-4 contains the evaluated numerical data presented in the corresponding panels. The raw data generated with micromagnetic simulations is too large for this dataset and is available upon request by the authors. Folder Fig-5 contains the experimental spectra measured with Brillouin-light-scattering microscopy as a function of power and time. Folder FIG-S1 contains the log file for the sample fabrication and scanning electron microscope (SEM) images. Important note for the SEM images: When acquiring the SEM images, the calibration of the Raith150 tool was off momentarily. This resulted in recording wrong scale bars with the images. The structure dimensions are known from the design file and were confirmed at another time after adjusting the calibration.
