As a postdoctoral researcher, you will work towards resolving how circularly-polarised phonons driven at resonance can induce ultrafast switching of magnetisation. This project is conducted at the HFML-FELIX facility and involves the development of novel laser-based experimental techniques and, subsequently, measuring how chiral phonons can ultimately drive magnetic switching.
Discovering how to control magnetisation at the highest possible speed while dissipating the least possible energy is crucial for the development of next-generation data-storage technologies. State-of-the-art theoretical proposals suggest that microscopic chiral vibrations of the lattice offer a powerful means to affect macroscopic magnetic order in a wide variety of systems. The goal of this project is to experimentally explore how magnetisation can be reversed using circularly-polarised optical phonons driven at resonance.
