제목 Control of Fe Oxide Particle Structures for Enhanced Magnetic Properties
초록 The iron nitride phase a"-Fe16N2 has been suggested as a possible rare-earth free permanent magnet candidate due to abundant amout of Fe and N on the earth, its large magnetocrystalline anisotropy, and large saturation magnetization. Thus, researchers have developed the various synthesis methods such as wet chemical, ball milling and plasma process etc. However, there is no report on the shape control of Fe particles to enhance the magnetic properties of a"-Fe16N2. In this study, we have synthesized Fe oxide particles with solid, hollow and rod structure, respectively. The magnetic properties were investigated after the reduction of the resulting Fe oxides, followed by nitridation.
This work was supported by the Industrial Strategic Technology Development Program (10062130, Theory-driven R&D for non-centrosymmetric structured rare-earth free Fe-based permanent magnet materials) funded by the Ministry of Trade, industry & Energy (MI, Korea)
