用X射线衍射和磁化强度测量研究了具有ThMn_（12）型结构的UFe_（10）Si_（22）单晶。观察到单轴各向异性、19.5 μ Bf.u. − 1的饱和磁化强度和1型一阶磁化过程，对于沿硬a轴沿着施加的场，与先前的粉末结果一致。由沿着难磁化轴的磁化曲线求得各向异性常数K1、K2和K3。一阶磁化过程的分析，通过同时测量磁化强度的纵向（α H）和横向（α H）分量，将其分配给总磁化强度的旋转。结果表明，铀亚晶格对该化合物的磁性有重要贡献。
UFe10Si2single crystals with ThMn12-type structure were studied by X-ray diffraction and magnetisation measurements. A uniaxial anisotropy, a saturation magnetisation of 19.5 μBf.u.−1and a type-1 first order magnetisation process, for fields applied along the hard a axis, were observed in agreement with previous powder results. The anisotropy constants K1, K2and K3were obtained from the magnetisation curves along the hard axis. The analysis of the first order magnetisation process, through the simultaneous measurement of the longitudinal (∥ H) and transverse (⊥ H) components of the magnetisation, assigned it to a rotation of the total magnetisation. The results indicate an important contribution of the uranium sublattice to the magnetism in this compound.
