| 摘 要： | The crystal structure and magnetic properties of SmFe9-x Cox(x = 0, 1, 3, 5) alloys were studied by X-ray powder diffraction(XRD) and magnetic measurements. The Th2 Zn17-type structure of the as-cast state is changed to TbCu7-type structure after quenching to a rotating molybdenum roll under certain velocity(12, 20, and 32 m s-1). The(002) XRD peak appears and a-Fe phase disappears when the Co is added up to x = 5. Saturation magnetization of SmFe9 under different temperature shows 9 % change(112–102 A m2 g-1) when the temperature is higher than 200 K. The saturation magnetization is 115 A m2 g-1and coercivity is 0.304 T at 5 K for SmFe9 alloys. Increased saturation magnetization and decreased coercivity can be obtained for Co added up to x = 5 at 5 K.
