FresnelLorentz_skyrmionDynamics.mib Raw frame data from Fresnel TEM aquisition of defect motion at skyrmion lattice domain boundary captured using the Medipix3. Details for import into ImageJ: Image type: 16-bit Unsigned Width: 256 pixels Height: 256 pixels Offset to first image: 384 bytes Number of images: 1000 Gap between images: 384 bytes micromagnetic_data.zip Folder - Contains raw simulation files consisting of energy density files (Edens_*.ovf), magnetisation files (m*.ovf), log.txt files and table.txt files. Folders within: - skyrmion_merge.out contains files used to create Fig. 4c and Supplementary Fig. 2d - skyrmion_split.out contains files used to create Fig. 4d and Supplementary Fig. 2e - skyrmion_lattice_5-7_defect.out contains files used to create Supplementary Fig. 1c - skyrmion_lattice_domainBoundary.out contains files used to create Supplementary Fig. 1d - skyrmion_merge_12nm.out contains files used to create Supplementary Fig. 2f fege.mib fege.hdr DPC data. The combination of the files fege.mib and fege.hdr provides DPC STEM data (acquired using Quantum Detectors MERLIN 1R detector) for each point in a 256 x 256 pixel scan. A suggested method for exploring the file contents is to use the libraries HyperSpy/PixSTEM(http://hyperspy.org/ and https://pypi.org/project/pixstem/) or fpd (https://pypi.org/project/fpd/) in Python.
