Ultrafast Magnetisation Dynamics for Future Data Storage

This PhD project investigates how light can be used to switch magnetisation on picosecond timescales and how computational physics can support future data-storage technologies. The research will develop theoretical and computational models to understand laser-driven magnetisation dynamics in ferromagnetic materials, including switching through magnetic circular dichroism and related ultrafast processes. The project will involve: developing computational models of laser-driven magnetisation dynamics studying how material properties affect switching behaviour running simulations and analysing results comparing theory with experimental measurements working with collaborators across theory, experiment, and application The project includes collaboration with the University of York, Radboud University, the University of Manchester, and Seagate Technology, and gives access to facilities for magnetic thin-film growth, ultrafast laser experiments, magnetic characterisation, and high-performance computing. This project is part of a Graduate Teaching Assistantship, so the successful applicant will also contribute up to 180 hours of teaching or research support activity each academic year.
