Next-generation Permanent Magnet Materials Group
We are developing post-neodymium magnets such as samarium alloy and metastable alloy in order to overcome the resource problem and low heat resistance of neodymium magnets, which are the key to EV motors. In particular, because the performance of magnets is significantly affected by microstructures, we focus on the creation of new powder metallurgy processes.
Group Research Theme
Low oxygen powder metallurgy process
Rare earth magnets that are sensitive to oxidation can be prepared by powder metallurgy process under extremely low oxygen conditions without exposure to the atmosphere.
Sm-Fe-N sintered magne
Rare earth magnet nanoparticles
Our developed thermal plasma technology is able to synthesize rare earth alloy nanoparticles, which has been difficult in the past. A sintered magnet with a coercive force of over 5T was realized from these nanoparticles.
