Giant energy product of a two-phase magnet with tabletlike inclusions

Influence of soft-phase to hard-phase ratio on energy product of a nanostructured two-phase magnet has been analyzed with micromagnetics. Below a certain critical size, the inclusion of soft phase not only reduces the consumption of rare-earth elements but also improves the energy product. Calculated energy product significantly depends on the shape of soft phase, and indicates that giant energy product of the tabletlike soft inclusions is feasible.
