This project is in collaboration with General Motors of Canada. It aims at identifying, characterizing and developing low-cost Fe-based permanent magnets for high temperature applications. Such magnets are needed for the automotive industry, mainly for the electric motors in addition to other automobile parts. This research will also benefit a wide range of industries such as aeronautical, motor production, electronic equipment and wind energy. Permanent magnets are also necessary for components used in national defense activities. The magnets that satisfy to some extent the current technological demands contain significant amounts of expensive rare earth elements. More importantly, currently there is almost complete dependence on foreign sources to supply these rare earth metals. In this project, the use of these metals will be minimized and the expensive rare earths (Nd, Dy and Sm) will be replaced with a more abundant and less expensive element such as Ce.
