Recent advances in SmFe(12)-based permanent magnets

To realize a sustainable society, ‘green technology’ with low (or even zero) CO(2) emissions is required. A key material in such technology is a permanent magnet because it is utilized for electric-power conversion in several applications including electric vehicles (EVs), hybrid EVs (HEVs), and tur...

description To realize a sustainable society, ‘green technology’ with low (or even zero) CO(2) emissions is required. A key material in such technology is a permanent magnet because it is utilized for electric-power conversion in several applications including electric vehicles (EVs), hybrid EVs (HEVs), and turbines for wind power generation. To realize highly efficient electric-power conversion, a stronger permanent magnet than Nd–Fe–B is necessary. One potential candidate is a Fe-rich SmFe(12)-based compound with a ThMn(12) structure. In this paper, the phase stability, structure, and intrinsic and extrinsic magnetic properties in both film and bulk forms are reviewed. Based on these results, a possible way to realize a strong SmFe(12)-based permanent magnet in bulk form is discussed.
