Abstract
A novel effective method of distinguishing between phonon and magnetic contributions into the total resistivity of 3d metals is presented. The method allows for the nonlinear character of interatomic forces and their change with temperature. Obtained results are important for quantitative estimates of the magnetic properties of ferromagnetic materials, including the nanostructured. This is illustrated by a calculation of the temperature behavior of s–d exchange interaction energy in 3d metals and by description of the temperature dependence of the resistivity of a one-threaded ferromagnetic nanowire made of Ni.
