The concept of an exchange-spring magnet, where a high remanence soft magnetic phase exchange couples to a highly coercive hard magnetic phase, provides a mechanism to produce permanent magnets with both an improved energy density as well as the potential to reduce consumption of rare earth materials by a factor of more than two. We have developed a technique which employs electrophoretic deposition to produce (near) net-shape SmCo5 magnets with an open architecture, which we infiltrate with an Fe-rich magnetically soft phase. This presentation will focus on recent advances in developing exchange coupling between the SmCo5 and Fe-rich phases when deposited in a format suitable for bulk production.
