Synthesis and magnetic properties of bulk α″-Fe16N2/SrAl2Fe10O19 composite magnets

2020/10/08

This work id a result of collaboration with the Mechanics of Functional Materials Division at the TU Darmstadt and Siemens AG, Corporate Technology. In the quest for hard-soft composite magnets, we present here the interesting case of mixing iron nitride and Sr-hexaferrite, where the uniaxial anisotropy of the ‘soft’ phase is larger than that of the hard phase. We have synthesized bulk hard-soft composite magnets from Al-doped Sr-hexaferrite SrAl2Fe10O19 sub-micron- and iron nitride α″-Fe16N2 nano-particles. Both powders have been mixed via ball milling, followed by compaction at low temperatures.
