摘要：
The method of calculation of the energy spectrum and magnetic phase diagrams of the systems with magnetic ordering is presented It is based on the cluster expansion method for the Green's functions. The results for crystals with b.c.c. lattice and half-elliptic (Hubbard) electronic spectrum are compared with each other. The contribution of Van Hove singularities to an electron-energy spectrum and magnetic-phases' arrangement is analysed. The behaviour of an electrical conductivity at magnetic ordering is studied.
