Abstract:
Hard magnetic Sm2Fe17Nx nanoflakes were prepared by surfactant assisted ball milling (SABM) at low temperature using liquid nitrogen cooling (surfactant assisted cryomilling). 2-methyl pentane was used as a milling medium and oleylamine as a surfactant. The morphology, structure, and magnetic properties of Sm2Fe17Nx were investigated using scanning electron microscopy, X-ray diffraction, and vibrating sample magnetometer, respectively. By comparing Sm2Fe17Nx nanoflakes produced by SABM at low temperature and at room temperature, we found that the former has many interesting features: more homogeneous morphology, smaller size, especially markedly increased remanent magnetization (Mr), saturation magnetization (Ms), and remanent magnetization ratio (Mr/Ms). These Sm2Fe17Nx nanoflakes have great potential to be used for preparing high performance bonded permanent magnets.
