Data for "Ultrafast formation of a large dynamic magnetic soliton"

Open data archive================= Paper title:Ultrafast formation of a large dynamic magnetic soliton This archive contains source-data tables, figure files, selected raw data,micromagnetic simulation files, and analysis utilities associated with thepaper. The data are organized primarily by the figure in which they are used. Archive status-------------- This is a working pre-upload version of the archive. The items listed under"Pre-upload checklist" should be resolved before the public Zenodo deposit. Directory guide--------------- Fig1/ Source-data tables and the PDF for manuscript Fig. 1. The schematic PDF was prepared in the free and open-source vector graphics editor Inkscape: https://inkscape.org/ Fig2/ Working folder currently containing five source-data tables and a PDF for the Ga:YIG spin-wave-emission figure. See the figure-numbering item in the pre-upload checklist. Fig3/ Source-data tables and the PDF for manuscript Fig. 3. The RawData/ subdirectory contains the original HDF5 measurement files and the M9-M6-Combined.py analysis script used for the time-resolved BLS data. Fig4/ Working folder currently containing two source-data tables for the Bi:YIG frequency-sweep figure. See the figure-numbering item in the pre-upload checklist. ExtendedDataFigs/ Source-data tables and figure files for Extended Data Figs. 1-7: ExDatFig1/ Bi:YIG sample characterization ExDatFig2/ Ga:YIG sample characterization ExDatFig3/ Linear dispersion relation and group velocity ExDatFig4/ Analytical-model profiles ExDatFig5/ Power- and frequency-dependent BLS intensity ExDatFig6/ Phase evolution during soliton formation ExDatFig7/ Time-resolved STXM data on Ga:YIG MuMax3Codes/ MuMax3 input scripts, analysis notebooks, and normalized antenna-field masks: BiYIG-4096x128-f11p0GHz-AmpSweep.mx3 GaYIG-Amp_8mT-FieldSweep-DE.mx3 Analysis_BiYIG-4096x128-f11p0GHz-AmpSweep.ipynb Analysis_GaYIG-Amp_8mT-FieldSweep-DE.ipynb STR_wirewidth_0.5um-analytic.ovf STR_wirewidth_2um-2025-12-11-analytic.ovf.ovf PythonTools/ LoadData.py Functions for reading MuMax3 OVF output files and loading single-component snapshot series for analysis. AntenaOVFcreatorAnalytical.py Utility used to calculate normalized stripline antenna fields. The script contains optional plotting and clipboard-export steps. See the dependency limitation in the pre-upload checklist. Data formats------------ CSV The figure source-data tables are comma-separated text files. Axes are included either as columns or as the first row and first column of matrix tables. Some files are currently encoded as Windows-1252; see the pre-upload checklist. HDF5 The raw time-resolved BLS measurement files for Fig. 3 are stored in Fig3/RawData/. Run M9-M6-Combined.py from that directory so that its relative file paths resolve correctly. The M9 measurement is shorter than the nominal acquisition grid expected by the script. M9-M6-Combined.py reports this and pads the missing tail with NaN values before analysis. OVF The antenna-field masks are OOMMF OVF vector-field files for use with MuMax3. They contain three field components with units of tesla. PDF and EPS The rendered figure files are included for reference. Extended Data Fig. 4 is supplied as EPS because the analytical-model plot was generated as a vector EPS figure. Software requirements--------------------- The Python analysis utilities use Python 3 and, depending on the workflow: numpy pandas matplotlib h5py tqdm plotly pyperclip jupyter The micromagnetic input scripts require MuMax3:https://mumax.github.io/
