Extended Data Fig. 3: Detailed overview of the magnetic state of the vortex loop containing Bloch points (presented in Fig. 3), shown in successive slices through the loop.
From: Experimental observation of vortex rings in a bulk magnet
The magnetization within each slice is represented by the streamlines. The colour scale in the top row indicates the \(\hat{x}\) component of the magnetization, while the colourscale in the bottom row indicates the \(\hat{x}\) component of the vorticity. The vorticity along the vortex core reverses between slices b and c, while the vorticity along the antivortex core reverses between slices c and d. f, The white isosurface, plotted along with the vortex loop, corresponds to mx=0 and separates regions of mx=+1 and mx=−1, thus highlighting the presence of a complicated domain wall structure. The Bloch points are located at the intersection of the loop with this isosurface (locations indicated by the dashed circles).
