High performance NiFe permanent magnets for electric motors and turbines

In this project we aim to establish a low-cost method to produce L1o-structured NiFe, which has magnetic properties comparable to the best rare earth magnets. Replacing the latter in electric motors in electric/hybrid cars and wind turbines will lead to not only large cost reductions, and hence greater adoption of these technologies with associated energy reductions, but also a reduction in RE metal production with substantial environmental benefits including a reduction in energy usage in their production. 

The novel approaches used to produce L1o NiFe include:

In addition, we will develop a cost-performance model for the material and perform a market analysis.
