Symposium Characterization of Materials through High Resolution Imaging
Presentation Title X-ray Imaging of Three-dimensional Magnetic Systems and Their Dynamics
Author(s) Claire Donnelly
On-Site Speaker (Planned) Claire Donnelly
Abstract Scope Three-dimensional magnetic systems promise significant opportunities for both fundamental physics, and applications [1,2]. However, their experimental realisation requires new characterisation techniques. We have developed X-ray magnetic nanotomography [3], providing access to the three-dimensional magnetic configuration at the nanoscale. In a first demonstration, we determined the three-dimensional magnetic structure within the bulk of a magnetic micropillar that contains vortices and antivortices, as well as Bloch point singularities [3]. In addition, the dynamic response of three-dimensional magnetic configurations is key. We have developed pump-probe X-ray magnetic laminography, providing access to the magnetisation dynamics of a three-dimensional magnetic system [4]. These new experimental capabilities unlock the elucidation of complex three-dimensional magnetic structures, and their dynamic behaviour.
