As part of a NEDO project, an academia-industry collaboration team including Tohoku University, the University of Tsukuba, and DENSO Corporation as the team leader, has succeeded in creating the world's first high-purity synthesis of FeNi superlattice magnet materials, in which iron and nickel are regularly arranged at the atomic level.

FeNi superlattice magnets are expected to have high magnetic functionality. This successful synthesis will significantly advance the practical application of these high-performance, rare earth-free magnets.

Going forward, NEDO will further evaluate the material-forming and molding method that is responsible for the magnet's high performance, with an ultimate goal of application of the FeNi superlattice magnet material as a permanent magnet for motors.

The details of this research were featured in the British journal Scientific Reports on October 16, 2017.
