| 摘 要： | 本文用中子衍射对Nd_2(Fe_(0.9)Si_(0.1))_(14)B在室温及77K进行了测量,用衍射峰的形状分析法进行了数据拟合。结果表明,在室温,Si择优占据4c,8j_1及16k_2晶位;Nd与Fe的磁矩平行于C轴排列。在77K,Si仍择优占据上述三个晶位。算得的Nd磁矩的方向偏离C轴37.8°。

| Abstract: | The neutron diffraction of Nd_2(Fe_(0.9)Si_(0.1))_(14)B has been measured at room temper-ature and 77 K. Their data were fitted by profile analysis method. From the data at room tem-perature it can be got that Si occupied preferentially the sites 4c, 8j_1 and 16k_2; the magneticmoments, both Nd and Fe, are parallel to C axis. From the neutron data at 77 K it can beshown that Si still occupied the same sites as the sample at room temperature, but the data fitwith Nd moments deviating C axis and Fe moments parallel to c axis is better than all mo-ments parallel to C axis. It seems to prove that the Nd spin reorientation takes place at 77 K. |
