Popis: An expression is derived for the phonon component of electrical resistivity using a four-band model which considers the electron contribution to conductivity from two 4s subbands and the hole contribution from two 3d subbands with differently oriented spins, using Mott's concepts in the relaxation time approximation. The expression obtained gives the dependence of resistivity upon electron state density at the Fermi level. The concentration dependence of resistivity is calculated for alloys of iron with chromium, manganese, cobalt, and nickel.
