摘要：

Exchange hardning 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 intereactions between the soft regions. For Sm2Fe17N3(2.5 nm)/Fe6SCo35(9 nm) multilayers an energy product as high as 1 MJ/m3 (120 MGOe) is predicted, with a rare-earth content of only 5wt%. Giant energy products may also be achieved in suitable cellular and disordered structures.
