摘要
研究了 Mn含量对金属间化合物 YFe12 - x Mnx结构和磁性的影响。 2 .0≤ x≤ 5.0范围内的 YFe12 - x Mnx 化合物具有单相 Th Mn12 型结构。随着 Mn含量增加 ,晶格常数 a、c和单胞体积 V增大 ,居里温度 TC和分子饱和磁矩μs单调降低。
In the present letter, the effect of Mn substitution on structure and magnetic properties of YFe 12- x Mn x compounds has been investigated. All the YFe 12- x Mn x compounds with 2.0≤ x ≤5.0 crystallize in the ThMn 12 type of structure.The lattice constants and the unit cell volume increase monotonously with increasing Mn concentration. The Curie temperature and the molecular saturation moments of YFe 12- x Mn x compounds decreases monotonically with increasing Mn content.
