/ Abstract
The authors unveil topological spin structures composed of skyrmion strings in a cubic centrosymmetric iron oxide that provides the missing experimental link between centrosymmetric lattices and a rich variety of helimagnetic order. This is the first observation of a three-dimensional topological spin texture in a bulk perovskite-type oxide, one of the most ubiquitous and important systems for oxide electronics. The study enlarges the family of topological spin textures and offers a promising route toward the design of novel oxide skyrmionics.
