Very small permanent magnets are desirable for use as sensors and actuators. There is a size gap in the production of magnets between thin films (<100 nm) and traditional bulk magnets (mm scale). Advanced manufacturing offers opportunities for producing such gap magnets where one or more of the dimensions falls within this intermediate range while minimizing material waste due to machining and breakage. This is particularly desirable for designing magnets with complex geometries and applying magnetic actuators to micromechanical devices. One challenge is that AM processes often destroy the very microstructure that makes magnets valuable. Here we will discuss the developing the processing of a class of CeCoFe based magnet alloys suitable for AM at fine length scales while retaining high coercivity and remanence. This work was performed under the auspices of the U.S. Department of Energy by Lawrence Livermore National Laboratory under Contract DE-AC52-07NA27344.
