Structurally disordered s-d model of magnetism in metals is investigated. The simplified model of binary alloy structure is offered, the structural correlation functions are calculated. The self-consistent equations for calculation of a spectrum, magnetization, electronic spin polarization and temperature of phase transition are obtained.

Long-wave spin excitations in the perfect s-d model are studied. The Hamiltonian of the model includes, apart from usually treated spin-electron processes, the Heisenberg exchange interaction of atomic spins and the Coulomb interaction of conductive electrons. Hartree-Fock and Tyablikov approximations are used for closing the hierarchy of equations of motion for the double-time Green functions. The equation for the magnon excitations spectrum in this approximation is obtained.
