Outline of Final Research Achievements

We have challenged the synthesis of the (Fe,M)16N2 nanoparticles which substituted Fe of Fe16N2 having high saturated magnetization with the transition element M to create the rare earth elements-free magnetic material. We chose Co, Ni, V, Cr, Mn, Al as a M element according to the theoretical calculation of magnetic anisotropy. After making α-(Fe,M)OOH as a starting material by neutralization oxidation process, we got α-(Fe,M) by reduction, finally we got (Fe,M)16N2 by nitrogenation. The production yield of α-(Fe,M)OOH and (Fe,M)16N2 are greatly affected by M element. High coercivities of 2000 Oe were finally provided in Co and Co-Al addition systems. It has been able to show that this material has the possibility as the hard magnetic material.

Academic Significance and Societal Importance of the Research Achievements

α-(Fe,M)OOHナノ粒子を出発原料として、続く還元、窒化によって(Fe,M)16N2ナノ粒子を合成するプロセスにおいて、還元条件が異なると(Fe,M)16N2を合成できない場合があり、相は同じでも組織が異なると(Fe,M)16N2が生成しないことが明らかになった。これは固相-気相反応によるNの格子間侵入型化合物の形成メカニズムについて大きな示唆を与えた。最終的にCoおよびCo-Al複合添加系で高い保磁力が得られ、今後急速に普及する電気自動車やロボット等に使用される磁石材料のレアアースフリー化に関して、この物質が大きなポテンシャルを有することを確認出来た社会的意義は大きい。
