摘要: Expressions for the transverse and longitudinal magnetic (spin) susceptibility of ferromagnetic metals, which have been derived from density-functional theory in local-density approximation, are simplified made practical computation through a transformation Fourier representation to an orbital representation. The method is applied calculation nickel at $T=0$. Results obtained spin-wave energies widths using semiempirical band structure.
