Atomistic simulations of advanced permanent magnet materials
Neodymium permanent magnets are ubiquitous in technologies from cars to wind generators due to their inherent efficiency in converting electrical power to mechanical motion or vice versa. Next generation rare-earth-transition metal permanent magnet materials based on the TmMn12 (RETM12) structure present an exciting opportunity to double the energy efficiency of the materials. Coupled with new motor designs this presents the possibility of doubling the power output of a wind turbine or range of hybrid car with the same battery size.
The aim of this funded PhD project is to develop new atomistic models of RETM12-based permanent magnet materials to predict their performance and understand the fundamental magnetic properties. These models will be used to guide industrial magnet production in collaboration with Toyota Motor Corporation and the MagHEM project to accelerate the development of next generation magnets with ultrahigh energy efficiency.
