Abstract
Exchange hardening of nanostructured two-phase systems composed of an aligned hard phase and a soft phase with high magnetization is investigated using a micromagnetic approach which accounts for interactions between the soft regions. For Sm2Fe17N3 (2.5 nm)/Fe65Co35 (9 nm) multilayers an energy product as high as 1 MJ/m3 (120 MCOe) is predicted, witb a rare-earth content of only 5 wt %. Giant energy products may also be achieved in suitable cellular and disordered structures.
