“…[15]) allow us to calculate the mean free path l. The calculation is based on the relation ρ=m(ne 2 τ) Making use of the spectrum (15), we calculate the concentration dependence of the Fermi-level, E F (x), the density of states (DOS), ν(x), the spin stiffness, D(x), and the whole magnon spectrum, ω(k,x), and the conductivity, σ(ω,x), both on the single hopping integral, Α, see [6].…”
