Fig. 5: Topologically protected strings and their path distribution function.
From: Three-dimensional imaging of topologically protected strings in a multiferroic nanocrystal
Three-dimensional images of topologically protected string defined as the path of each vortex core for the (111) reflection throughout the reconstructed h-DyMnO3 nanocrystal. a Slice through the reconstructed h-DyMnO3 nanocrystal showing coincidence points of strings with vortex cores. b Strings shown with identical orientation as shown in (a). c Reoriented view of strings. d Alternative view of a slice through the reconstructed h-DyMnO3 nanocrystal showing coincidence points of topological strings with vortex cores. e Strings shown with identical orientation as shown in (d). f Reoriented view of topological strings. g Path Distribution Function (PthDF), g(r), which describes the distribution of distances between pairs of strings, independent of orientation. Error bars are twice the standard deviation.
