Magnetism and Light

⠀⠀⠀⠀Our Magnetism and Light project is a materials discovery initiative aimed at achieving light switchable magnetism and spin control in functional materials.  Switching magnetism and manipulating spins with light remains a considerable challenge that is currently materials limited.  A paradigm shift is needed to achieve useful light-controllable magnetism.  Despite efforts going back nearly 50 years, single-phase materials are unlikely to be the solution.  Rather, heterostructures or complex mesoscale materials offer the best opportunity for achieving new mechanisms for switching magnetism with light and for discovering transformative materials that will enable new technologies.
