| Abstract | 利用中子粉末衍射技术确定了77K温度下化合物中Si原子占位和原子磁矩，研究了DyFe10Si2化合物低温下的结构与磁性．结果表明，在77K化合物的易磁化方向与ab平面之间有较小的夹角．采用全势能线性缀加平面波（（L）APW）＋局域轨道（10）方法计算了DyFe10Si2及其氮化物的磁性和间隙原子效应，分析了化合物中间隙N原子在Si原子不同占位时的作用．结果表明，N原子的杂化作用能提高化合物的饱和磁矩（不显著），使其居里温度有显著的提高（15％-20％）. |
| Other Abstract | The crystal sites of Si and atom magnetic moment in the DyFe10Si2 were determined by neutron powder diffraction at 77K temperature in order to investigate the structure and magnetic properties. The results showed that there is a small angle between the easy magnetization direction and ab plane in DyFe10Si2 at 77 K temperature. The magnetization and interstitial atom effects in DyFe10Si2Nx compounds and its nitride were calculated by the new developed full-potential linearized augmented plane wave （LAPW） and local orbital （Io） based on standard APW method and the action of N in the compounds was analyzed along with the different occupied sites of Si atom. The results showed that saturation magnetization is enhanced by the introduction of N atom （but the effect is very weak） and the Curie temperature is increased about 15%-20%. |
