本文用密度泛函理论研究了铀化合物U_2Pd_2Sn、U_3X_4、UPdSn、UX_3、UPdSn和UPtGe的复杂磁性结构。一个通用的方法，它允许治疗主要不同的磁性状态的基础上，这些化合物的一个物理概念。这一概念将U系统中的强自旋-轨道耦合以及晶体和磁性结构的对称性与磁性构型的稳定性联系起来。
The density functional theory is applied to study the nature of complex magnetic structures in various Uranium compounds: U2Pd2Sn, U3X4, UPdSn, UX3, UPdSn and UPtGe. A general approach is developed which allows to treat principally different magnetic states of these compounds on the basis of one physical concept. This concept relates the strong spin-orbit coupling in the U systems and the symmetry of the crystal and magnetic structures to the stability of the magnetic configurations.
