对具有非共线自旋构型的晶体的能带结构计算的三种最普遍的方法（KKR、APW和紧束缚）进行了概括。结果表明，使用广义不对称可以在许多物理上有趣的情况下推导出一个长期方程，该方程的维数仅比具有相同晶格的共线磁铁的长期方程的维数高两倍。通过一个算例说明了这些方法的可行性。[俄语文本被忽略]
A generalization is given of three the most universal methods of energy band structure calculations (KKR, APW, and tight binding) in the case of crystals with noncollinear spin configuration. It is shown that the use of generalize dsymmetry allows in many physically interesting cases to deduce a secular equation, which dimension is only two times higher than the dimension of the secular equation for a collinear magnet with the same crystal lattice. The possibilities of the methods are illustrated by a model example. [Russian Text Ignored]
