High Temp High Energy Product Permanent Magnet Material

The main objective of this program is to develop a new class of high performance hard magnetic materials that will maintain an energy product of 30 MGOe or greater at temperatures up to 450 °C. These novel magnetic materials are greatly needed for the "more electric" airplanes and space vehicle applications where a high operating temperature is a strict requirement. The approaches to be used for the development of these magnets are mainly focused on exchange-coupled hybrid composite/nanocomposite materials (also known as metamaterials) consisting of two hard magnetic phases and possibly some soft magnetic phases where the overall performance of the composite is greater than the sum of the individual components. Research in Phase I will be focused on optimization of material compositions and processing parameters to obtain the desired properties.
