最近的实验表明,Sm 5 Fe 17相的Sm-Fe快淬薄带具有高的矫顽力。为了阐明这一现象,我们进行了磁化强度测量和Sm 5 Fe 17的熔体快淬薄带的显微结构研究。研究发现,Sm_5Fe_(17)快淬薄带的磁性能为单畴型,高磁性能的Sm_5Fe_(17)快淬薄带具有直径为10- 20 nm的细小晶粒。
Recent experiments indicate that Sm–Fe melt-spun ribbons with the Sm5Fe17 phase exhibit high coercivity. To elucidate this phenomenon, we performed magnetization measurements and microstructural studies of Sm5Fe17 melt-spun ribbon with coercivity. We found that the coercivity of Sm5Fe17 melt-spun ribbon is single-domain type, and that Sm5Fe17 melt-spun ribbon with high coercivity possesses fine grains of 10–20nm in diameter.
