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 and 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. 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 the 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. Folder S2 contains the BLS spectra for different frequencies of the gyration excitation. Folder S4 and S5 contain the simulated spectra for the respective shown panels. Folder S6 contains the power sweeps and time trace BLS data. Fig S9 contains the shown BLS data.
