Skyrmions in magnetic materials — •Jonathan White — Paul Scherrer Institut, Switzerland

Research into magnetic Skyrmions currently attracts significant attention in topological condensed matter physics. Individual Skyrmions display a non-trivial twisted spin structure which, unlike simple ferromagnetic and antiferromagnetic spin structures, is described in terms of a finite topological index. We will introduce how this finite topology endows Skyrmions with remarkable properties, which moreover display a novel interplay with the general properties and dimensionality of the host magnet. We will also explain how the fascinating aspects of the physics of Skyrmions motivates the general expectation that topological spin structures will become pivotal components for future information technology and data storage.
