本文详细研究了Ga取代Sm（R，Mo）12化合物中的部分Fe对其结构和内禀磁性的影响．其中包括：Ga在Sm（Fe，Mo）12化合物中的原子占位，不同Ga取代对SmFe10．7－xMo1．3Gax化合物的晶胞常数，Curie温度，饱和磁化强度，磁晶各向异性的影响．实验结果表明：Ga替代增加晶胞体积，降低Curie温度，减小饱合磁化强度，降低Fe原子的平均磁矩；随Ga含量的提高，SmFe10．7－xMo1．3Gax化合物由单轴向锥面各向异性转变
The structural characterization and intrinsic magnetic properties of the compounds SmFe10.7-x Mo1.3Gax have been investigated in great detail, which included the lattice parameters, Curie temperature TC, saturation magnetization σs, and magnetocrystallize anisotropy. The results indicate that Ga occupies 8j and 8f sites, and substitution of Ga for Fe in SmFe10.7Mo1.3 leads to the expansion of the lattice constants a, c and unit cell volume V, the monotonical decrease of the Curie temperature TC, and the decrease of saturation magnetization and the Fe moments. The magnetocrystalline anisotropy changes from uniaxial to conical plane.
