Abstract

The synthesis of Sm₂Fe₁₇N₃ magnetic particles has been vigorously studied because of their superior magnetic properties. Here, we developed a novel method to form Sm₂Fe₁₇N₃ magnetic particles with relatively high coercivity (1.3 T), which were formed from Fe₃O₄SmO_x coreshell nanoparticles using a reduction-diffusion process, followed by in-situ nitridation. This method would provide not only smaller Sm₂Fe₁₇N₃ particles with higher coercivity but also other rare-earth containing materials.
