Dr Luke Turnbull - PhD student

University Of Durham

Luke Turnbull joined the Skyrmion Project in 2018 as a PhD student in the Centre for Materials Physics at Durham University, working under the supervision of Professor Peter Hatton.

His PhD focused on using resonant soft x-ray imaging methods at x-ray synchrotron facilities to image topological magnetisation states in single crystal lamellae of chiral magnetic systems. This included studies on systems reported to host biskyrmion, antiskyrmions and other exotic spin textures. His experimental work has led to several publications with collaborators in and beyond the Skyrmion Project.
