We use the dynamic spin-fluctuation theory to study spin-density correlations in ferromagnetic metals above the Curie temperature. We calculate the spatial spin-correlation function, dynamic susceptibility and local magnetic moment. The dynamic susce

Consistent treatment of symmetry in the tight-binding method, developed by Egorov et al [Phys. Stat. Sol. 26, 391 (1968)] for crystals with two atoms per unit cell, is generalized to crystals with several atoms per unit cell. A method is presented fo

We propose a numerical continuation method for a nonlinear system that consists of scalar and functional equations. At each parameter step, we solve the system by a modified Gauss–Seidel method. An advantage of this method is that the system is div

We consider the electron-phonon interaction in the framework of dynamic spin-fluctuation theory and obtain an expression for the self-energy part that depends explicitly on the spin fluctuations and lattice vibrations. We illustrate the theoretical r

We study magnetic short-range order in Fe and Ni above the Curie temperature using the nonlocal dynamic spin-fluctuation theory with self-consistent calculation of the self-energy. We calculate the spatial correlation function of Fe and Ni at nearest

We obtain an expression for the neutron scattering cross section in the case of an arbitrary interaction of the neutron with the crystal. We give a concise, simple derivation of the Debye–Waller factor as a function of the scattering vector and the

We obtain expressions for the spatial spin-density correlator and for effective and local magnetic moments in the dynamic spin-fluctuation theory. We derive formulas for the magnetic scattering cross section in the theory of itinerant electron magnet
