| 中文摘要 | Structural and magnetic properties of off-stoichiometric 2:17-type compounds Sm2Fe16MAl2 (M = Mn, Mo, Ni) and their carbides were studied using X-ray powder diffractometry, magnetization measurement, thermomagnetic analysis, and differential thermal analysis, All these compounds had the Th2Zn17-type structure. When Mo was added into the parent compound Sm2Fe17Al2, the unit cell was enlarged by 0.4%, larger than those of M = Ni, Mn, However, the Curie temperature T-c and saturation magnetization M-s of Sm2Fe16MoAl2 were lower than the parent because Mo atom had not effectively increased the separation of Fe-Ire pairs. When C was added to the parent and the Sm2Fe16MAl2, an increase in the volume of the unit cell and T-c, and a decrease of M-s were observed, The carbide of the parent had the largest cell dilation of 2.11%, which also exhibited relatively high T-c and M-s, When M = Ni, its carbide had the largest M,, indicating that the addition of Ni had enhanced the ferromagnetic coupling, It was also found that Sm2Fe16MnAl2C1.5 was more stable than the other compounds, and that it decomposed at about 950 degreesC. |
